I have OCD with hypochondria, so I'm constantly worrying about my health. I also compulsively check things on my body to make sure I'm okay, and blah blah. You get the idea.
Most of my dreams are actually nightmares and they often involve my health. I've always had this morbid fear of vomiting/coughing up blood, having rectal bleeding, etc. I get nightmares of things like that actually happening. I dream other scary things, too. Last night was particularly horrifying for me. And as I was worrying in the dream and fretting, I was also doing my regular OCD crap. Blah, this is long and stupid...but I think you get my point. If I have one. Yes, I think I do my OCD stuff while asleep. And it's sad because I would at least like some stress relief when unconscious, but that doesn't even happen.
