It sounds good, but I don't think that my dreams 'time' [Morning, Noon or night] have anything to d owith my mood or else, if I go by your idea, I'm almost always happy before I go to sleep and that is definately not true. But since I've never tried to pay attention to it before, I will now and see if it's true. And as for doing a task set by a DC, I'd do it if it sounds interesting but otherwise I'd rather be doing something else that's much more fun.

I don't think that this idea would apply to dreams that last a few days long now would it? Or else I'd be considered one moody person ^^
