the astral plain is a whole other world... spiritual not physical. first u have to get the sight...you'd find that in the witches bible. you're exposed to everything and anything...major risk is dying...seriously. there's astral travelling and astral roaming... whether it be past present or future its up to u...u can go back and forth. its really time and energy consuming. its really dangerous so before u try it make sure you're FULLY prepared.

try and get Ophiel's book on it. very practical and effective.
