I'm kind of finding some of these that are listed to be ambiguous. I mean, some of these might have references similar to the state or action of astral projection, but that doesn't neccessarily mean that each was intended by the artist to mean as such. The state of dreaming, and also just the state of freedom and release from stess (which are all common means of inspiraction for songwriting) bring about imagery of free floating or falling free, and release. Like I said, some just seem to be ambiguous, ha.
