Environmental patterning
Environmental patterning can be described as the experience of certain textures such as carpets, asphalt, and dense vegetation drifting into progressively complex geometric patterns that are always clearly comprised of the original material which they are manifesting from. These structures tend to be primarily symmetrical in nature, but also include form constants, fractals, and disorganised geometric patterns.
Environmental patterning is very common under the influence of moderate to heavy dosages of psychedelic compounds such as LSD, psilocin, and mescaline. It is also often complemented by the simultaneous experience of symmetrical texture repetition, geometry, and drifting.
