LD when in dream motion

I've noticed that when ever I get the feeling of motion in a dream I almost emediatly recognize that it's a dream. I was wondering if anyone else experienced this also? I was hoping I could some how be able to increase the frequency of this feeling since so many other techniques seem to not work for me. I belive it's because my dreams (which is btw really vivid but not lucid) very ordinary to waking life. I usually dream of my friends, family and work so nothing 'odd' really happens in them.

Both of my latest LD's (short but very real) where triggered when I fell into some sort of abyss.
Anyone got any tips?

I'm glad to hear it's more then me who experienced this. Tonight I woke up after after 3 hours and one very vivid LD. I had a dream where me and a friend tried to document dreams with a video camera. He was suppose to tape me while I fell from the sky (which I did). The falling sensation allerted me and I actually came to think (in the dream) about this topic. The dream was clear as crystal but unfortunately not under my control :( As I came closer to the ground the dream faded and I woke up.

I also noticed that I slept on the side today. Usually I always sleep on my back but because of the heat in my bedroom I felt more comfortable on the side. Maby this had something to do with it as well :?
