Just because it's physical doesn't mean that it has nothing to do with the occult, though. Otherwise, why would this website have a shop? Why bother to have a wand, or crystals, or tarot cards? Why would many distinguished spiritual traditions have chemognosis (the use of iboga root or peyote cactus or fly agaric, in the case of Delphi Oracles, sulphur) to help their spiritual visions? Sometimes fasting or a vegetarian diet can affect the spirit, even though food in the body is only physical.
I believe that consciousness can be a liminal area, like in faelatry traditions where there are "doorways" at dusk or dawn, or bridges, or thresholds. Sometimes, the doorway is in the mind between waking and sleeping.
All that said, I did try to keep it scientific. I would shuffle a pack of cards and leave them at the top of the bookshelf without looking at them. I shouldn't be able to see them, I decided, unless I could astral project. But the way to move out of body was difficult for me, so I could never go where I wanted to go. I could wall through walls, but I couldn't get past walls that weren't physically there.
It's a very silly place.
One time, I tried to peek behind my friend's shoulder (she was physically in the same room, borrowing my computer while I meditated) and there was this force field around her that pushed me away. It made me wonder if there was a danger in astral projecting, not only leaving one's own body "open to possession" (that I don't believe can happen anymore because neuroscience actually does have so much to do with our experiences, however we interpret that) but getting sucked into somebody else's body if they don't have as strong a personality as my friend (which I believe is what gave her such a strong aura.)
