Cause when you astral travel you goto the plane where demons and angels reside, it's not a 'vacational' trip.. There are many threads based on this.. look for mine on the dream scape... But your other experiences seem to tend towards telekinetic.. hrmm maybe not that.. but something else.. anyways, moving things with your mind.
Perhaps you are the first of the 'next' generation..
