Gargoyle: I created the thread with one title, but reconsidered my subject line before posting. I really wanted the "Dream music" title for the thread, to minimize the sort of topic drift that has already occurred.

And if you're rambling on about what I think you are, it is quite usual for both men and women to become aroused during the dream state without there being any overtly sexual content in the dream; it's a physiological thing, though one that (to me) makes as much sense as why we get the urge to urinate when our hand is stuck in warm water.
