I don't know much about them, but I have a friend who has had them all her life. I'll send her here if she signs on tonight.

Anyway, are these dreams still recurring, or are there any similar dreams that you still have? If so, they're dreamsigns. Remember the situation you're in, and everytime you think about it, check if you're dreaming. When you're in the dream, you should remember to check after a while and you'll realize you're dreaming.
