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. For example, during this experience a person may begin seeing music, tasting colors, hearing smells, or any other potential combination of the senses. 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.
Synaesthesia is commonly induced under the influence of heavy dosages of psychedelic compounds, 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.
