Psychedelic refers to substances or experiences that alter perception, mood, and cognitive processes. These effects can lead to visual and auditory hallucinations, changes in thought patterns, and a heightened sense of awareness. Common psychedelic substances include LSD, psilocybin (found in magic mushrooms), and DMT. The term is also used to describe a genre of art and music that reflects these altered states of consciousness. Psychedelic art often features vibrant colors, intricate patterns, and surreal imagery, while psychedelic music incorporates experimental sounds and extended improvisation, aiming to evoke a similar sense of expanded perception.
