Drifting + 25I-NBOMe
25I-NBOMe is known to produce drifting, a visual effect. The 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.
About Drifting
Drifting is experienced as a pervasive sense of slow, fluid motion within one's visual field. Surfaces such as walls, ceilings, wood grain, and fabric appear to breathe rhythmically — expanding and contracting as if alive. Text on a page may swim or crawl, faces may subtly morph, and the edges of objects can appear to flow like liquid. The effect is most noticeable when gazing steadily at a fixed point, where the peripheral and central visual fields begin to undulate and shift in organic, wave-like patterns.
At threshold doses, drifting presents as a subtle breathing or swaying of surfaces that can easily be dismissed as imagination. As dosage increases, the motion becomes unmistakable — walls ripple like disturbed water, patterns in carpets and textiles flow like rivers, and the boundaries between objects may blur and merge. At high doses, drifting can become so intense that the entire visual field appears to be in constant, overwhelming motion, making it difficult to read text or focus on fine details.
Drifting can be broken into several distinct subtypes. Breathing involves surfaces rhythmically expanding and contracting.Flowing describes textures streaming in a consistent direction, like watching a river current.Melting is the perception of solid objects appearing to liquefy and drip downward.Morphing involves objects gradually changing shape, particularly noticeable in human faces. These subtypes often co-occur and blend into one another at moderate to high doses.
The mechanism behind drifting is thought to involve serotonin 5-HT2A receptor agonism in the visual cortex, particularly in areas V1 and V2 responsible for processing edges, motion, and texture. Psychedelics increase the excitability of visual cortical neurons and disrupt the brain's predictive coding mechanisms, causing the visual system to generate motion signals from static input. The Default Mode Network's reduced top-down control over sensory processing allows these aberrant signals to reach conscious awareness unchecked.
Drifting is most prominently produced by classical serotonergic psychedelics such as LSD, psilocybin, mescaline, and DMT. It is also commonly reported with dissociatives like ketamine and DXM at moderate doses, as well as cannabis in high doses or in psychedelic-naive users. NBOMe compounds and the 2C-x family are particularly known for producing pronounced drifting effects. Deliriants may also produce drifting, though typically of a qualitatively different character.
Drifting is generally considered a benign visual effect and poses no direct physical danger. However, intense drifting can impair one's ability to navigate physical environments safely, read text, or operate machinery. It can contribute to feelings of disorientation or anxiety in unprepared individuals, particularly when combined with other distortions such as depth perception changes. Harm reduction advice includes remaining in a safe, comfortable environment and having a sober sitter present during experiences with significant drifting.
