The astral plane, also called the ‘astral realm’ or the ‘astral world’, is a non physical plane of existence postulated by classical, medieval, oriental and some modern esoteric philosophies and mystery schools. It is the realm of the celestial spheres, entered into or crossed by the soul on the way to being born and after death, and is generally believed to be populated by non-corporeal spirits and other immaterial beings. The spiritual adept is said to be familiar with The Astral, by disengaging from the physical body and exploring at will.
There is an increasing opinion in present day metaphysical and philosophical circles that ‘Cyberspace’ is an aspect of The Lower Astral.”
