I thought it was happened in the movie.
You may experience it true to life.
Did this happened to you? This will explain.
Astral projection (or astral travel) is a term used in esotericism to describe an intentional 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. The modern terminology of "astral projection" was coined and promoted by 19th-century Theosophists. 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). There is no scientific evidence that there is a consciousness or soul which is separate from normal neural activity or that one can consciously leave the body and make observations, and astral projection has been characterized as a pseudoscience
