TQC, for the past two weeks or so, I have been having very vivid, and often unpleasant dreams (but I wouldn't say they're nightmares). For this reason, I don't think my sleep is very restful, and I wake up exhausted. I'm getting the right amount of sleep hour-wise, and I'm not going through any new stresses or changes in my life.
So why is this happening?! And how can I make it stop?
All theories, speculations, and suggestions are welcome!
ETA: I'm not taking any kind of medicine or drugs.
