I'd make sure to pay attention to my surroundings, because if you close your eyes and forget about the dream, it could destabilize. Don't spin to change locations unless you maintain this awareness of your surroundings and visualize it well. If you're just spinning to stabilize, do it slowly; it's just to take in the scenery and get visual input from the dream. Everything in the dream is dependent on your expectations so if you act like you can't walk, talk or fly, you won't be able to. Don't think of yourself lying in bed or sleeping.

Good luck!
