Synaesthesia - PsychonautWiki


(Redirected from Synesthesia)

Synaesthesia (also spelled synesthesia or synæsthesia) is a condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway.[1] For example, during this experience a person may begin seeing music, tasting colors, hearing smells, or any other potential combination of the senses.[2] At its highest level, synaesthesia becomes so all-encompassing that each of the senses become completely intertwined with and experienced through all of the other senses. This is a complete blending of human perception and is usually interpreted as extremely profound when experienced. It is worth noting that a significant percentage of the population experience synaesthesia to varying extents during every day life without the use of drugs.[3][4]

Synaesthesia is commonly induced under the influence of heavy dosages of psychedelic compounds,[5] such as LSD, psilocybin, and mescaline. However, it is seemingly most commonly experienced under the influence of stimulating psychedelics such as the 2C-x, DOx, and NBOMe series.
