I've been having trouble making my lucids last. I've had 7 lucids so far, and they all just seem to end after about 10 seconds. This isn't because I get too excited (or at least I don't feel I'm getting excited), the dream just deteriorates after a while and I lose it. So I was thinking to spin at the very moment I attain lucidity, to make sure I'm properly grounded in the dream. Is this a good idea? Are there better ways to do this?
