I need some help, Im very confused with my dreams.

[Nightfallspy]

1. Ok, so whenever I have a dream or something that doesn't seem to work out in the dream. I do this thing the feels like I'm doing it in my sleep to. I close my eyes, and almost like vibrate my head a little. Then usally I feel myself in bed, lazy and tired to get up, but nothings happening, then I just lift my head and I'm up. Also, I dont seem to wake up from dreams if I have a nightmare or something that scares me... The dream just goes on... Why is that? Also..... 2. Alright so this comes to me in ALOT of my dreams, I want to lucid dream so much that I think I'm tricking myself. Usually in the dream, I say "I must be dreaming" And then attempt to fly. Then I end up flying, but unable to control anything and when I'm real high, I just fall, when I hit the ground I don't wake up, I think I just start another dream...? Im confused .
