Wow, I was wrong. You can "project".
Hang on, my Pineal gland has opened a portal. Wait, it's James Randi and he's laughing.
Seriously, if you want to know about the Pineal gland, look in a medical book. You'll find its involved with Circadian rhythms, metabolism and hibernation and contrary to popular "myth" believers, it is not the "seat of the soul". This quite common belief developed from its location in the brain. Without the foundation of brain science which we thankfully have today, people from the past concluded, ahem, wrongly but understandably, that it "must" have supernatural powers. Of course they believed all sorts of crazy things back then. Not like today where we are all so modern and smart. Right?
Astral projection is merely an extension of that myth spun into modern lingo.
Don't get upset. I just figured you might as well be informed. have a good day.
out.
