OBE, or Out-of-Body Experience, is a phenomenon where a person feels as though they have left their physical body and are observing it from a distance. This experience can occur during sleep, meditation, or near-death situations. People often report a sense of floating or traveling to different locations while being aware of their surroundings. Research into OBE has explored its psychological and neurological aspects, suggesting that it may be linked to brain activity during altered states of consciousness. While some view it as a spiritual experience, others consider it a result of brain function, such as dissociation or hypnagogic hallucinations.
