Gates Of Light

Not sure if I should post here or somewhere else.

I had a very unusual experience a couple of months ago and it still has a toll on me.

Me and a friend (she is very spiritual and magick oriented, you could call her witch in fact) had some space cakes. I have to admit I definitely overdosed, but the effect went beyond I am sure.

I tripped very hard (my friend was watching over me and she wasn't under the effects) but it went over the usual bursts of colours and paranoia. I still have roughly a clear memory of most of it. I started to say things: first of all I started chanting and doing repetitive symbols in the air, the same over and over. I can remember that I was seeing light and I was trying to write some sort of symbols with my hands. Then the other interesting thing is that at one point I saw some gates made of light and on the other side an island suspended on either sea or a sea of stars. I had the feeling that I wasn't allowed to cross as it was a one way journey, I still feel the pull sometimes if I focus, my friend tells me is a astral projection but I'm not sure, I'm totally a newbie on everything! I kept repeating that I understood everything, that I could see everything and that everything was connected. My friend tried to ask questions but I was very lucid when telling her that she couldn't know, cause she couldn't see. Now, I'm not keen on repeating the experience cause it was pretty violent, I mean, beautiful but not sure how much from it was from the drug and how much from a real psychic experience. What do you think? What could have happened? What language was I chanting in? What place was with this gates and the island? Any clues?
