Astral projection (or astral travel) is a term used in esotericism to describe a willful out-of-body experience (OBE) that assumes the existence of a soul or consciousness called an “astral body” that is separate from the physical body and capable of travelling outside it throughout the universe. The idea of astral travel is ancient and occurs in multiple cultures. It is sometimes reported in association with dreams, and forms of meditation. Some individuals have reported perceptions similar to descriptions of astral projection that were induced through various hallucinogenic and hypnotic means (including self-hypnosis).

The multiverse (or meta-universe) is a hypothetical set of various possible universes including the universe which humans live in. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, the physical laws and the constants that describe them. The structure of the multiverse, the nature of each universe within it, and the relationships among these universes vary from one multiverse hypothesis to another. Multiple universes have been hypothesized in cosmology, physics, astronomy, religion, philosophy, transpersonal psychology, and literature, particularly in science fiction and fantasy.
