Can you astrally project in to another dimension?

I wonder if anyone can teach me a little about what I experienced this morning? Or anyone can relate?
A few months ago I felt that I astrally projected just about two feet out of my body whilst in a certain state of slumber, but I was in the same room and situation that I was in whilst 'sleeping', i.e. in this dimension.
This morning I felt myself falling in to this same conscious yet meditative state of sleep. Being completely aware of it, I consciously decided to raise myself out of my body and did with ease. I felt completely awake and was analyzing every feeling and experience I was having along the way. I was floating and felt no mass at all. I spotted a shelf full of drinking glasses and seemed to know I could pass through them. I raised my hand and waved them through the objects. I noticed that when my hands passed through a 'solid', it had a similar feeling to wading through water. A very slight resistance. Have people documented this ever?
I would keep waking inbetween these experiences and decide I would allow for the same state to take me over, then attempt to leave my body again and again. I began to pass through walls and ceilings, and started training myself to 'somersault' in mid air. Now I know this sounds strange as I was not in physical form ,but I imagine that my brain still thought of me as 'solid' as it has always known itself this way. What do you think? I had the sensation of a somersault and felt like I manipulated my muscles in order to do it, though saw no legs etc?
The thing is, I knew exactly where I was on the earth in my physical form - I was sleeping on my bus in the yard, yet my experience as my spirit was not there, and I couldn't way this up. Where was I? Was it just a dream of astral projection? Or could I have entered another realm? There is no shelf of glasses in the bus. Yet it was as clear and crisp as day. I felt like my eyes could not be MORE open. I kept testing the experience lucidly and logically. Was it just a lucid dream?
There's more. Two kittens and a rabbit (?!!?) appeared right in front of me. I reached out and touched them. They were looking right at me. I couldn't comprehend what was going on. During this 'episode' I was back on the bus and I looked out of the windows and could see all sorts of weird and wonderful creatures not of this world. The feeling was that they were of MY creation rather than animals from another realm. As clear as crystal. I questioned my own mind but they didn't disappear.
When I awoke I thought about this and realised that it must have been the act of manifestation?!? With no training in this and no way of censoring my thoughts, strange and disturbing things were appearing. I can see why magic/witchcraft can be dangerous due to this. An uncontrolled mind may manifest what it does not want.
Anyway I would love some feedback on this please if anyone has any? It seems like a very profound lesson but I am not experienced enough to understand it fully myself.
Thank you. Deb xxx
