I used to frequently dream that all my teeth had crumbled away. Then I read somewhere that it symbolises a fear of my life getting out of my control. It seemed believable because I am an occasional control freak. Then I found at this site that it might mean I was anxious about my physical appearance (which means about 80% of adult woman probably have this dream), or worshipping the wrong deity.
The boy asserts, however, that all it means is that I was worried about being overdue for a dental check-up. And he's not joking either.
Another dream I've had in the past is one in which I am immobilised and there is a strange man in the room or in my bed. It was pretty damned freaky, almost as scary as the dream in which I was being suffocated (and I was - by my sleep apnoea). The same website says that dreaming of being paralysed means I feel my life is not in my control (snap!).
Or maybe I was simply a victim of alien abduction that night.
I do know for certain that, if I dream about having a wee, then it's pretty certain I need to get out of bed and go to the toilet.
