A powerful psychoactive drug that breaks down subconcious barriers and will make your mind race through the corridors of human perception. While under the influence you'll often hear people say "Dude Im trippin so hard" many many times as a way to come to terms with the phenomena that is occuring. Visual filters in the brain are broken down to let raw, unfiltered data in. It is usually hard to talk and move while your under the influence, so a suggestion would be to find a comfy chair, put some Phish on, and perceive.
