Pattern recognition enhancement from DOM

Pattern recognition enhancement can be described as an increase in a person's ability and tendency to recognize meaningful patterns within vague, ambiguous, or random visual stimuli. This effect builds upon the innate human capacity for pareidolia — the well-documented tendency to perceive faces, figures, and other recognizable forms in random arrangements of shapes, textures, and shadows. Under the influence of this effect, this natural perceptual tendency is significantly amplified, causing patterns to emerge from visual noise with much greater frequency, clarity, and detail than would occur during ordinary sober perception.

During this effect, remarkably detailed images may appear to be embedded within natural scenery such as tree bark, rock formations, carpet textures, and cloud formations. Everyday objects may suddenly resemble human faces, animals, or other recognizable forms. Wood grain patterns may resolve into intricate landscapes, ceiling textures may appear to contain hidden portraits, and the random visual noise of static or poorly lit surfaces may seem to be teeming with meaningful imagery. Critically, these perceptions occur without any actual visual distortion or hallucination taking place — the external visual input remains unchanged, but the brain's interpretive processing of that input is dramatically enhanced.

At lower intensities, one may simply notice an increased tendency to spot faces in objects or recognizable shapes in clouds. At higher intensities, the perceived patterns become increasingly detailed and compelling, and the mind may further exaggerate these initial recognitions through the hallucinatory effect known as transformations, in which perceived patterns begin to actively morph and develop beyond simple pareidolia into full visual hallucinations.

Pattern recognition enhancement is most commonly induced under the influence of mild to moderate dosages of psychedelic compounds such as LSD, psilocybin, mescaline, and 2C-B. It is often one of the earliest visual effects to manifest as a psychedelic comes on, appearing even at sub-hallucinogenic doses. It can also occur with cannabinoids, particularly at higher dosages, and with certain dissociative compounds.

This effect is often accompanied by other coinciding effects such as visual acuity enhancement, colour enhancement, and symmetrical texture repetition. The enhanced pattern recognition frequently serves as a foundation upon which more complex visual phenomena build as dosage increases, making it a gateway effect that transitions into more elaborate visual experiences at higher intensities.
