1-i deal w absolutly no bull in here.you have a question post it.Do not as*ume anthing if u dont understand.2-please dont pi*s me off.I have low tolerence for stupidity.Astral projection has nothing to do with ghosts,or fighting them.Astral projection has everything to do with Ur spirit and your frame of mind,and meditation.shamins use astral to go on visions quests to help them with problems there particular tribe is having.they meditate on a higher level.astral planes consist of 8 or more realms(just like a spiritual plane does).it depends on your knowledge.u can travel throu these levels.ghosts do and sometimes they get left behind or lost in their paths.our paths has everything to do with astral travel and how far we go with it.some like to battle,some want a higher psychic knowledge..some just want a deep meditative state.
