Don't know what exactly happened

This happened last night, so it's still pretty fresh.
I've been "warming up" through meditation and trying to program myself a couple of days before, and just yesterday I started trying seriously to exit my phisical body and project. I have to say that I am trying simoultaneously to Lucid Dream as well with no results...

So Yesterday the focusing and relaxation went ok. Then suddenly started feeling a little pressure on my stomach like pulling down, or as if one of my cats walked over it; this didn't bother me but then I freaked out when I started feeling what I think is the vibration state, because It felt like I was floating on a pool and the little moves I did didn't match my muscles... then I remembered what people say abouth the possibility of seeing evil spirits and dead people, and I don't know, I panicked and started praying stopping the process until I felt asleep.

But then comes last night. I tried to relax and focus for a while, and failed, but then woke up around 3 am and, after praying a little to kill the fear, tried again. Then came the magic... and I still can't believe what happened. When I got the same weird vibration feeling after the pressure on my stomach,  I did the simplest method I've found everywhere that is just to move and get up.

And.. whoa... I felt so so so free! I had to do it in two steps, first the upper part of my body and then my legs, and I had to try harder so I could separate them... It was like breaking out of a cocoon. My skin was over sensitive, and it was like my body was made out of electricity... I was so so happy! I was scared of looking at my bed but I peeked anyway and there I was, still sleeping; also, my room was more iluminated as usual. Then a girl that was very much like me, or that was the sensation I got, because she didn't scare me and I knew I could trust her, greeted me quickly and giggling, rushed me through the wall to another place.

But this part is what I don't really get and makes me doubt of my experience being an astral projection or just a super motivated lucid dream. That place I appeard in and I had never been to, was like a girls club; It was placed in a sort of temple, that reminded me of ancient greece or rome, but noone inside was arcaic looking at all!

The girl who guided me there, did it so I could see all the things I could do, like a welcoming event. I thought that she might have taken me there because I really didn't know where I wanted to go when I exited. So, there, I could materialize stuff, bring back to life memories and we talked about all my worries and troubles, al freely, and we were really happy; we drank, we sang, we laughed, a lot like a ladies night.  I spent there what I felt like hours, but then I woke up as if had been just a dream and I was extremely confused. It was 5 am by then.

There are many things I don't know...
Who was that girl whose name I don't know, where did she came from at all?
Did the projection fail and turned into an obvious lucid dream?
Or if it was a real astral projection, when did I get back to my body?
I could see my body, and ah, those feelings, that freedom I got when I think I exited my body were so intense and real... I had never dreamed of something like that... I am really really confused. I need answers!  :-\

What I'm more confused about is the constant feeling of not knowing if I'm awake anyway, or that I'm aware and seeing things that are just not there... like I saw a very big squirrell noone else could notice on my daily walk today, or the sensation of the trees and wind, everything like breathing around, or something watching us and stuff like that.
So now is sleeping time again and I'm going to try again tonight, but I don't know if I'll get any experiences tonight.

Thanks for any advice you can give me.  :)

Much love.
