Astral projection is a practice where individuals believe they can separate their consciousness from their physical body and travel to other planes of existence or dimensions. Some people who practice astral projection believe that it can provide access to higher realms of consciousness beyond the physical world. However, the scientific community does not have concrete evidence to support these claims. It is important to approach astral projection and similar practices with caution and an open mind, while also being aware of the potential psychological and physical implications.
