Sex dream, interrupted

I'm in a dream and a girl comes up to me while I'm working on something, and sits down on the floor next to me. I look over at her, and apparently doing my best Captain Kirk imitation, I say "My God, you're beautiful" (she really was). Just after we begin kissing there is a bolt of lightning in the physical world -- a thunderstorm is rolling into town -- and the dream is gone. I try to lay there for a minute, hoping I can get back to the dream, but that one bolt of lightning is followed by several more, and I know that dream has come and gone.

P.S. -- I remain amazed at the images (and sensations) the brain can create. To my knowledge I've never seen this girl before, but she was indeed beautiful.
