The astral plane is a non-physical realm of existence, said to exist beyond the physical world, where the soul or consciousness can travel independently of the body, most often described in the context of dreams, meditation, or a practice called astral projection. It's generally described as a place where ordinary physical rules don't apply.

Dream analysis sometimes references the astral plane when a dream feels unusually vivid or real, since some traditions describe especially lucid or memorable dreams as a form of astral travel rather than an ordinary dream.
