A<unk>  (known colloquially as a trip) is a temporary altered state of consciousness induced by the consumption of a psychedelic substance (most commonly LSD, mescaline, psilocybin mushrooms, or DMT). For example, an acid trip is a<unk>  brought on by the use of LSD, while a mushroom trip is a<unk>  brought on by the use of psilocybin.<unk> s feature alterations in normal perception such as visual distortions and a subjective loss of self-identity, sometimes interpreted as mystical<unk> s.<unk> s lack predictability, as they can range from being highly pleasurable (known as a good trip) to frightening (known as a bad trip). The outcome of a<unk>  is heavily influenced by the person's mood, personality, expectations, and environment (also known as set and setting). Researchers have interpreted<unk> s in light of a range of scientific theories, including model psychosis theory, filtration theory, psychoanalytic theory, entropic brain theory, integrated information theory, and predictive processing.<unk> s are also induced and interpreted in religious and spiritual contexts.
