When I took 5 hits of acid a little over a month ago I came out of it knowing I saw and learned a lot or possibly all of the knowledge and understanding of the universe that I completely forgot as soon as I came back to earth(physical realm). I feel like that knowledge can be accessed by taking large doses of LSD or Mescaline, by allowing your consciousness to be connected with your soul instead of the physical realm. What thing do you know for sure exists that you can never tangibly touch or see? That is your soul. Your soul is what I believe is what makes you, you. By "soul" I mean an existing representation of your mind that resides in the 4th dimension, especially since it's in the 4th dimension we can't really see what our soul is. When ever you think things through your head it is your soul processing thoughts to your brain in the physical realm, while your soul has a separate existence elsewhere. So your brain is really a window to the physical realm for your soul and we do our everyday things feeling comfortably connected to our soul at all times. In a way the physical realm blinds us from realizing what we really are. In this case I don't put to question whether a soul exists or not, as long as you think for yourself then you have a soul. So as I said earlier while you are having an out of body experience your consciousness is not in the physical realm but rather in the 4th dimension. In the 4th dimension you can see, or so to speak, think of everything that has or will happen. But if you're able to see everything that happens at any time or any idea thought up from our universe, then that means your soul is the universe. Because how could when you are in the consciousness of your soul, be able to see everything that ever was from our universe? When I was in the 4th dimension in my trip I was able to speak to god and speak to(as how I remember understanding it during the trip) other souls of people that were currently taking LSD, Mescaline or DMT. In the 4th dimension I knew that I was in a plane of field with other souls. The other souls all told me that when they were in the physical realm they always wanted to be here(as in, with your soul) but they told me I might regret going there for the sake of the amount of knowledge I was given that I might not like after learning. They also scared me by telling me that I might not be able to return to the physical realm and in the end I will regret ever getting there. I've been piecing this all together ever since my trip.
