For me it's usually something I'm anxious about but during the day I can control how frequently I think about it and I have techniques to relax.

At night I am at the mercy of my mind. The thing I am anxious about will play out completely, with different scenarios and differing levels of anxiety over and over and over and over and over. I will wake up sometime, usually really early in the morning, and not be able to fall back asleep because my mind literally goes straight back into these invasive dreams. I will try meditating and everything and as soon as my mind starts drifting off it goes straight to the invasive anxiety dream.

It's terrible... anybody else? Does anybody have any suggestions for techniques to get it to stop?
