Visual disconnection from Dextromethorphan

Visual disconnection is the experience of becoming progressively distanced and detached from one's own sense of sight. It sits at the intersection of visual suppression and dissociative phenomenology — rather than vision becoming distorted or enhanced, it is gradually withdrawn, as though the connection between the eyes and conscious awareness is being systematically severed. The result is a spectrum of effects that progresses from mild visual impairment to a state of complete perceptual blindness.

At its lower levels, visual disconnection manifests as a constellation of related suppressive effects. Vision may become blurry, doubled, or sluggish in its frame rate. The ability to mentally process and interpret visual information degrades (a state closely related to visual agnosia). Colors may appear washed out. The overall impression is of vision becoming "distant" — still technically functional but no longer feeling like a direct, immediate connection to the external world. Users often describe this as looking at the world through progressively thicker glass, or as though their visual feed is being transmitted from a remote camera with increasing latency.

At higher intensities, the disconnection becomes all-encompassing. Visual input may be reduced to vague blobs of light and shadow, and eventually the distinction between open and closed eyes disappears entirely. The individual can no longer tell whether they are seeing anything at all. This state represents a complete perceptual disconnection from the sense of sight, and it is at this threshold that many users report finding themselves immersed in what is commonly known as a "hole" — a dark, expansive hallucinatory void that feels as though it exists outside of normal physical reality. The most famous example is theketamine "K-hole", though this phenomenon occurs with other dissociatives as well.

Visual disconnection is a near-universal effect at moderate to high doses of dissociative compounds such as ketamine, PCP, DXM, and methoxetamine. It typically progresses alongsidecognitive disconnection andphysical disconnection, creating a comprehensive detachment from all aspects of ordinary sensory experience. The effect is strongly dose-dependent and is generally reversible upon the substance wearing off, though the experience of complete visual blackout and void-immersion can be profoundly disorienting and existentially challenging.

Harm reduction note: Complete visual disconnection renders a person functionally blind and unable to navigate their environment. This creates significant fall risk and vulnerability. Anyone using dissociatives at doses that may produce this effect should be seated or lying down in a safe, supervised environment before the onset.
