Oooh Dreamweaver

I'm trying to figure out what's better or worse. Lately I have been having very stressful realistic nightmares. I wake-up all tense but feel better knowing it was all just a dream. Last night I had this beautiful vivid dream that seemed so real and was full of love and happiness. I woke up and realized it wasn't real and got very depressed. So is it better to have a night of bad dreams and wake up to knowing it isn't real or to have a very happy dream only to wake up and realize it isn't real? Man, I miss my abstract crazy dreams that have nothing at all to do with real life. Hey subconscious, can we bring those back into the rotation?
