Touch everything you see. It makes the dream more real and grounds me there so I consider it my whole reality for as long as I'm there. Don't think about anything else, letting your mind wander, but what's happening now, and what you are perceiving now in the dream. Your reality is only what you are focusing on at any given present moment when awake or in a dream.
Spinning would be the complete opposite and I don't do that either. It may help to change dream scenes, but not helpful if you want to stay focused on where you are.
