Everyone else has given the advice I would have.
Maybe your brain feels it's in a safe place and can process all the stresses you've recently gone through.
Ha! I'm going with the theory that my brain is just trying to mess with me, because hello, my life is a bit stressful right now, so I would really rather not have any more stress dreams! However, I am taking a small measure of comfort that the stress dreams are of the zombie apocalypse variety, instead of the I'm stuck working retail again flavor.
