DOM produces 63 documented subjective effects across 7 categories.
Full DOM profileDOM arrives with the slow, inexorable certainty of a tide. For the first two to three hours, there is almost nothing to report beyond a mild body buzz, a slight tightening in the stomach, and perhaps a barely perceptible brightening of the visual field. The legendary patience required by DOM begins here, in this deceptive calm before the storm. By the third hour, the experience begins to gather momentum. A deep, resonant stimulation builds in the body, different from the sharp push of shorter-acting amphetamines. It feels tectonic, as though something enormous is shifting beneath the surface of consciousness.
When the peak finally arrives, typically between four and six hours after ingestion, it does so with a profundity that can overwhelm even experienced psychonauts. The visual world transforms utterly. Colors do not merely brighten; they appear to reveal hidden dimensions of themselves. The green of a tree contains infinite shades, each one distinct and meaningful. Geometric patterns of extraordinary complexity emerge from every surface, but they have a depth and solidity that sets them apart from lighter psychedelics. Patterns appear to exist not on surfaces but within them, as though the molecular structure of matter itself has become visible. The experience has been described as seeing the underlying code of reality, and while that metaphor sounds grandiose, it captures something essential about DOM's character.
Cognitively, DOM at its peak produces a state of profound, almost overwhelming depth. Thoughts are not merely accelerated but deepened. Questions about identity, existence, time, and meaning arise with an urgency and weight that can be transformative or terrifying. The emotional landscape is vast and unpredictable. Ecstatic wonder, existential dread, oceanic peace, and searing vulnerability may all visit within the same hour. The body, meanwhile, maintains its driven stimulation: elevated heart rate, jaw clenching, dilated pupils, and a warmth that radiates outward from the core. Movement feels both purposeful and slightly mechanical.
The extraordinary duration of DOM is its most defining characteristic. The peak alone can last six to eight hours, and the total experience spans fourteen to twenty hours, sometimes longer. The comedown is a marathon of slowly diminishing intensity, during which the mind gradually releases its grip on the deeper layers of perception. Colors remain vivid for hours after the visuals proper have faded. Sleep is impossible until the very end, and when it finally arrives, it is deep and heavy. The following day often carries a sense of having been somewhere genuinely profound, accompanied by a bone-deep tiredness that demands rest.
A distinct decrease in hunger and desire to eat, ranging from reduced interest in food to complete disinterest or even physical revulsion at the thought of eating. This effect can persist for many hours beyond the primary experience.
Bodily control enhancementBodily control enhancement is the subjective feeling of improved physical precision, coordination, and dexterity — a sense of heightened mastery over one's own body that can make movements feel fluid, deliberate, and effortless.
DehydrationA state of insufficient bodily hydration manifesting as persistent thirst, dry mouth, and physical discomfort, often caused by increased sweating, urination, or simply forgetting to drink water during substance use.
DiarrheaDiarrhea is the occurrence of frequent, loose, or watery bowel movements as a side effect of certain psychoactive substances, resulting from either direct GI irritation or pharmacological alterations to gut motility and fluid absorption.
Increased blood pressureIncreased blood pressure (hypertension) is an elevation of arterial pressure above the normal 120/80 mmHg baseline, commonly caused by stimulants, vasoconstrictors, and substances that activate the sympathetic nervous system, posing cardiovascular risks that increase with dose and pre-existing conditions.
Increased bodily temperatureIncreased bodily temperature (hyperthermia) is an elevation of core body temperature above the normal 37C (98.6F) baseline, caused by substances that increase metabolic rate, impair thermoregulation, or promote sustained physical activity, and representing one of the most dangerous physical effects when severe.
Increased heart rateA noticeable acceleration of heartbeat that can range from a subtle awareness of one's pulse to a forceful, rapid pounding felt throughout the chest, neck, and temples. This effect is among the most commonly reported physiological responses to psychoactive substances and often accompanies stimulation, anxiety, or physical exertion during intoxication.
Increased salivationIncreased salivation (hypersalivation or sialorrhea) is the excessive production of saliva beyond what can be comfortably swallowed, commonly occurring with psychedelic tryptamines and certain antipsychotics as part of a broader parasympathetic activation pattern.
Muscle crampMuscle cramps are sudden, involuntary, and often painful contractions of muscles that occur as a side effect of certain psychoactive substances, particularly stimulating psychedelics and stimulants.
NauseaAn uncomfortable sensation of queasiness and stomach discomfort that may or may not lead to vomiting, often occurring during the onset phase of many substances.
Physical euphoriaAn intensely pleasurable bodily sensation that can manifest as waves of warmth, tingling electricity, or a full-body orgasmic glow radiating outward from the core. This effect is often described as one of the most rewarding physical sensations available through psychoactive substances and is a primary driver of the recreational appeal of many substance classes.
Pupil dilationA visible enlargement of the pupil diameter (mydriasis) that can range from subtle widening to dramatic saucer-like expansion where the dark pupil dominates the iris. This effect is one of the most recognizable signs of psychedelic and stimulant intoxication and directly contributes to light sensitivity, enhanced color perception, and the characteristic "wide-eyed" appearance.
SeizureUncontrolled brain electrical activity causing convulsions and loss of consciousness -- a life-threatening medical emergency requiring immediate help.
StimulationA state of heightened physical and mental energy characterized by increased wakefulness, elevated motivation, and a subjective sense of vigor that pervades both body and mind. Users often report feeling electrically alive, with a buzzing readiness to move, talk, and engage that can range from a pleasant caffeine-like lift to an overwhelming, jittery compulsion to act.
Teeth grindingAn involuntary clenching and rhythmic grinding of the jaw muscles, known clinically as bruxism, that produces a compulsive need to clench, chew, or gnash the teeth together. This effect can range from a subtle tightness in the jaw to forceful, repetitive grinding that can cause significant dental damage and jaw pain during and after the experience.
Temperature regulation disruptionImpaired thermoregulation causing unpredictable fluctuations between feeling hot and cold, with risk of hyperthermia or hypothermia.
VasoconstrictionA narrowing of blood vessels throughout the body that produces sensations of cold extremities, tingling in the fingers and toes, and a general feeling of circulatory restriction. Users may notice their hands and feet becoming pale, numb, or uncomfortably cold, sometimes accompanied by a sense of tightness in the chest or head.
A visual phenomenon in which a faint, ghostly imprint of a previously viewed image persists in the visual field after the original stimulus has been removed or one has looked away. These lingering visual echoes are significantly more persistent, vivid, and detailed than normal physiological afterimages, often retaining color and form for several seconds or longer and overlaying themselves onto whatever one currently views.
Autonomous entityThe perception of contact with seemingly sentient, independently acting beings that appear within hallucinatory states. These entities may communicate, display emotions, and behave with apparent intelligence and purpose beyond the user's conscious control.
Brightness alterationPerceived increase or decrease in environmental brightness beyond actual illumination levels, common with stimulants and psychedelics (brightening) or sedatives (darkening).
Colour enhancementAn intensification of the brightness, vividness, and saturation of colors in the external environment, making the world appear dramatically more colorful. Reds seem redder, greens seem greener, and all hues appear richer and more distinct than during ordinary perception.
Colour shiftingThe visual experience of colors on objects and surfaces cycling through continuous, fluid transformations, shifting from one hue to another in smooth, seamless loops. A green surface might flow through blue, purple, red, and back to green in a mesmerizing animated sequence.
Depth perception distortionsAlterations in how the distance of objects within the visual field is perceived, causing layers of scenery to appear exaggerated, rearranged, flattened, or warped in spatial depth.
DiffractionThe experience of seeing rainbow-like spectrums of color and prismatic halos embedded within bright light sources and reflective surfaces, caused by pupil dilation altering how light enters the eye.
DriftingThe visual experience of perceiving stationary objects, textures, and surfaces as appearing to flow, breathe, melt, or shift in position. Drifting is one of the most fundamental and commonly reported visual distortions under the influence of psychedelic substances, serving as the perceptual foundation upon which many other visual effects are built. It manifests as a fluid, organic sense of motion embedded in otherwise static visual fields.
GeometryThe experience of perceiving complex, ever-shifting geometric patterns superimposed over the visual field or visible behind closed eyelids. Geometry is widely considered the hallmark visual effect of psychedelic substances, ranging from simple lattice patterns and honeycombs at low doses to infinitely complex, self-transforming fractal structures at high doses that can feel profoundly meaningful and awe-inspiring.
Internal hallucinationVivid, detailed visual experiences perceived within an imagined mental landscape that can only be seen with closed eyes, ranging from fleeting imagery and abstract scenes to fully immersive, dream-like environments with autonomous narratives and entities.
Pattern recognition enhancementAn increased ability and tendency to perceive meaningful patterns, faces, and images within ambiguous or random visual stimuli such as textures, clouds, and surfaces.
Perspective distortionsDistortion of perceived depth, distance, and size of real objects, making things appear closer, further, larger, or smaller than they actually are.
Perspective hallucinationA hallucinatory phenomenon in which the observer's visual perspective shifts from the normal first-person viewpoint to alternative vantage points — including third-person (seeing oneself from outside), bird's-eye, or omniscient perspectives — during both internal and external hallucinations.
Scenery slicingThe visual field fractures into distinct, cleanly cut sections that slowly drift apart from their original positions before resetting, as if reality has been sliced by an invisible blade into geometric pieces that briefly separate and rearrange.
Settings, sceneries, and landscapesThe perceived environment in which hallucinatory experiences take place, ranging from recognizable locations drawn from memory to entirely novel alien landscapes, ancient civilizations, cosmic vistas, and impossible architectural spaces.
Symmetrical texture repetitionTextures appear to mirror and tessellate across surfaces in intricate, self-similar symmetrical patterns that maintain detail at every scale. Most prominent in peripheral vision on rough surfaces.
TracersMoving objects leave visible trails of varying length and opacity behind them, similar to long-exposure photography. Trails may match the object color or appear in other hues.
TransformationsObjects and scenery undergo perceived visual metamorphosis, smoothly shapeshifting into other recognizable forms over seconds. Patterns morph into faces, animals, and imagery.
A complete or partial inability to form new memories or recall existing ones during and after substance use, ranging from minor gaps in recollection to total blackouts encompassing hours of experience.
Analysis enhancementA perceived improvement in one's ability to logically deconstruct concepts, recognize patterns, and reach novel conclusions, often accompanied by deep states of contemplation and an abundance of insightful ideas.
AnxietyIntense feelings of apprehension, worry, and dread that can range from a subtle background unease to overwhelming panic attacks with a sense of impending doom, often amplified by the substance's intensification of one's existing mental state.
Conceptual thinkingA shift in the nature of thought from verbal, linear sentence structures to intuitive, non-linguistic concepts that are felt and understood rather than spoken by an internal narrator.
ConfusionAn impairment of abstract thinking marked by a persistent inability to grasp or comprehend concepts and situations that would normally be perfectly understandable during sobriety.
Immersion enhancementA heightened capacity to become fully absorbed and engrossed in external media such as music, films, video games, and art, with an amplified suspension of disbelief and a deepened emotional connection to the content being experienced.
Memory suppressionA dose-dependent inhibition of one's ability to access and utilize short-term and long-term memory, ranging from mild forgetfulness to a profound inability to recall personal identity, biographical information, or the context of the current experience.
Novelty enhancementA feeling of increased fascination, awe, and childlike wonder attributed to everyday concepts, objects, and experiences, as if perceiving the world for the first time.
Panic attackA panic attack is a discrete episode of acute, overwhelming fear or terror that arises suddenly and peaks within minutes, accompanied by distressing physical symptoms including rapid heartbeat, shortness of breath, chest tightness, trembling, dizziness, and a profound sense that one is dying, going insane, or losing control.
ParanoiaIrrational suspicion and belief that others are watching, plotting against, or intending harm toward oneself, ranging from mild unease to overwhelming terror.
Personal bias suppressionA decrease in the personal, cultural, and cognitive biases through which one normally filters their perception, enabling more objective self-examination and worldview analysis.
PsychosisPsychosis is a serious psychiatric state involving a fundamental break from consensus reality — characterized by firmly held false beliefs (delusions), perception of things that are not there (hallucinations), disorganized thought and speech, and a loss of the ability to distinguish internal mental events from external reality.
Thought accelerationThe experience of thoughts occurring at a dramatically increased rate, as if the mind has been shifted into a higher gear. Ideas, associations, and internal dialogue cascade rapidly, often outpacing the ability to articulate or fully process each one, producing a subjective sense of heightened mental velocity.
Thought connectivityA state in which disparate thoughts, concepts, and ideas become fluidly and spontaneously interconnected, revealing patterns and relationships that are normally overlooked. The mind weaves together seemingly unrelated subjects into a unified web of associations, often producing novel insights or a profound sense of conceptual coherence.
Thought loopsBecoming trapped in a repeating cycle of thoughts, actions, and emotions that loops every few seconds to minutes. Short-term memory lapses cause the sequence to restart.
Time distortionSubjective perception of time becomes dramatically altered — minutes may feel like hours, or hours pass in moments. Can manifest as either dilation or compression.
WakefulnessAn increased ability to stay awake and alert without the desire to sleep. Distinct from stimulation in that it does not elevate energy above a naturally rested baseline.
Auditory distortion is the experience of sounds becoming warped, pitch-shifted, flanged, or otherwise altered in their perceived qualities without any change to the actual sound source. Familiar sounds may seem alien, stretched in time, or layered with unusual resonances, creating a surreal and sometimes unsettling soundscape that departs significantly from sober auditory perception.
Auditory enhancementAuditory enhancement is a heightened sensitivity and appreciation of sound in which music, voices, and ambient noise become richer, more detailed, and more emotionally resonant. Subtle sonic details that would normally go unnoticed — the texture of a guitar string, the breath between a singer's words, the layered harmonics of a chord — become vivid and captivating.
Auditory hallucinationAuditory hallucination is the perception of sounds that have no external source — hearing music, voices, environmental noises, or abstract sonic phenomena that exist entirely within the mind. These range from faint, ambiguous whispers at the edge of perception to fully formed, complex musical compositions or conversational speech that can feel completely real and externally sourced.
Auditory misinterpretationAuditory misinterpretation is the brief, spontaneous misidentification of real sounds as entirely different sounds — ambient noise interpreted as voices, mechanical hums perceived as music, or random environmental sounds heard as words or familiar patterns.
Scenarios and plots are the narrative structures that emerge within hallucinatory states — coherent or surreal storylines involving autonomous characters, unfolding events, and immersive settings that can feel as real and consequential as waking life.
SynaesthesiaStimulation of one sense triggers involuntary experiences in another — seeing sounds as colors, tasting textures, or hearing visual patterns. A blending of sensory channels.
A profound dissolution of the sense of self in which personal identity, memories, and the boundary between self and world completely vanish, leaving only pure undifferentiated awareness.
Entity contactPerception of encountering autonomous beings or presences during psychedelic states, ranging from vague presences to fully realized communicating entities.
Existential self-realizationA sudden, visceral realization of the profound significance and improbability of one's own existence as a conscious being within the universe, often accompanied by overwhelming awe and a fundamental shift in perspective about life and reality.
Unity and interconnectednessA profound sense that identity extends beyond the self to encompass other people, nature, or all of existence. Boundaries between self and other dissolve into felt oneness.
