Synaesthesia

Synaesthesia (also spelled synesthesia or synæsthesia) is defined as a blending, merging or mixing of the senses. For example, alterations to sensory perception such as seeing music, tasting colours, hearing smells or any other possible combination of the senses are all possible. At its highest level, synaesthesia becomes so all-encompassing that each of the senses become completely intertwined and experienced through all of the other senses. It is a complete blending of human perception and usually interpreted as extremely profound when experienced.

This effect is triggered spontaneously within most of the classical psychedelics. It is seemingly more common on stimulating psychedelics such as LSD or the 2C-x family.
