Stress Dreams

I've been consistently having stress dreams this last couple of nights and it's pissing me off cuz I have no idea why I'm so stressed out. They're all centered around my boyfriend being unhappy with me, but I know he's not. I've told him about my dreams and he assures me that I haven't done anything to make him upset and that he would tell me if I did. I think I'm just nervous cuz this is the healthiest relationship I've ever been in and I'm terrified I'm gonna fuck it up somehow. Ugh. Stress sucks.
