weird experiences.. need some enlightenment

[DreamWolf590]

So, I am sort of new at lucid dreaming, but as soon as I started trying to have them I am noticing my dreaming is significantly different. I don't keep a journal .. I know I should be but I just don't have the will power to write as soon as I wake up but anyway ... I will usually have a lucid experience once a week, what normally happens is, im dreaming, i realize it and say "i'm dreaming!" I go through the sleep paralysis (even though i can move if i want to.) Then lucidly I wake up in my room and I can't leave my bed. I try to get out but my head feels like it's 100 pounds and every time I stand up I appear back in my bed until i give up and make myself awake for real. My next weird experience i had last night, I was dreaming and realized it, but instead of sleep paralysis I awoke lucidly in my room ran out the window and started flying, I can't remember like 90% of the dream, but I met whom I presume to be my spirit guide, its a very beautiful girl, my dream girl. (even though she looked different, I first met my guide in a non lucid dream.) I asked her if she was real and she replied yes. I asked when will I meet you, she said I can't tell you. So what I'm wondering is; is this really just all in my head or is there a greater understanding of this dream world that I havent figured out? And how can I get out of my room if im stuck.
