I think theres definately spirtual aspects to some drugs such as shrooms, and salvia, because i've experienced similar feelings while dreaming, and dreaming to me is your spirit travelling the earth, or wherever you might be in your dream,and If its a foreign location, its somewhere in the world. I've actually started re-having dreams i thought about while on shrooms, very odd feeling. I also see alot of foreign symbols,and writings, and pictures of, what i think was a culture long ago. Or mabye its just the way i perceive things, it could be the drug just fucking with my head.

Either way, I love these things
