Astral projection is the ability to leave your body. Everyone leaves their body at night, but before they do leave, they have to put the physical mind to sleep. Most people don't remember this, but when the physical mind is asleep, the subconscious takes over, and this is usually when you do your astral projection. In other words, everybody does it, but they just don't remember doing it.
