What happens during an out-of-body experience?

According to Osho, in an out-of-body experience you may find yourself standing outside, watching your body lying there. Re-entry needs no effort—simple intention pulls you back. On return you feel intense, unnatural hunger because the unattended body rapidly loses energy, becoming almost dead. Eating grounds you—food acts like a paperweight—helping your inner space settle. Don’t fear; there’s a time-limit before harm.
