Werid Feeling

I was going to the store to get a drink with my friend then I went to the bathroom. Suddenly I blacked out for a minute then woke back up. I was still standing during the black out. When I woke up I suddenly felt very tired and like I was about to pass out. I told my friend (he's psychic too. I'm a girl by the way), and he said he didn't know what was wrong with me. I came out and I could automatically see the auras of the trees and some people. Then I got a really weird headache and I felt a bit nauseous (not like I had to barf or anything. It's not actually). I usually have to sit and concentrate before seeing the auras. And it felt like I was floating. I also looked in the sky and I saw spirits and other psychic things. I was so scared and my friend didn't know what to do. I just went to sat down and it mad it a bit worse. I pinched myself REALLY hard and didn't feel anything. The mark went away after 5 minutes or so. I closed my eyes for a bit and I felt the opposite. This has happened to me twice before in the past but this one was severe. Was I in an astral projection? If I was, that would be really strange because I didn't do the things in order for me to project. By the way I still feel the same now but its not as bad now. Sorry if my wording/typing is strange. Did I travel to a different dimension or something? It was like I was dreaming, but I never went to sleep. To be honest I am not that experienced at being psychic. I only know auras, manifestation, astral projection and I know what my element is (water) but I have no idea how to control it. I also feel like nothing is really happening right now. Someone please help, I just want to know what is happening.
