I thought this might be an interesting topic to see what others have to say about. Here's mine:

During my last successful WILD, I heard a loud rush in my ears that sounded much like a reverse cymbal. I then felt as if all of my top teeth were being yanked out all at once. Needless to say, it hurt like hell. I tried to move but obviously, my body wasn't responding. It seemed like forever but was probably closer to lasting about five seconds. I thought that because I was trying to move that I was still awake after this happened, but it turned out that I was in a dream .

This was the most intense (and painful!) experience with SP I've had so far. I'm interested to see what other LDers, especially WILDers, have to say.
