Dream: Disturbing and Thrilling

Every have a dream that's so disturbing and thrilling that you can't get it out of your head all day? I had one of those last night. Every time I pause I find myself thinking about it. And I'm not sure I want to be doing so. It wasn't horrible, the dream. It was wonderful, really. Just wondering why I found the subject matter so wonderful. Anyhoo... I have very few dreams lately. Maybe that's why I'm fixating on this one? Because I can actually remember it for a change.
