For example, one way of maintaining and strengthening the lucid experience is supposedly spinning around in place with your arms spread. When I do that, I find a dream sensation that feels a bit like my arms trying to move out from under my pillow or caught in the sheets. I then wake up shortly after that.
Other times I'll know I'm lucid and can do some tricks, but still feel a bit limited, whether by the dream or my beliefs of what I think I can do in the dream. I cannot manifest scenery or people. Mostly I can get a small hop glide for flying, sometimes I can shoot a magic projectile. This may be due to limited control and practice.
