I just don't know where to begin with this one.
Possible trigger:
Basically, it involved, as far as I can recall, my brother and I as kids. He was making some really depressing-as-heck Charlie Brown-related stuff, I was also kind of working on some projects, and my parents were kind of wondering why I didn't do something for my little brother. Now the triggering part actually comes in because there's one part where I try to commit suicide -- though it's like I'm an adult here, not a kid -- and my mom stops me in time, and then there's a horrifying moment where my kidself is actually physically abused for being "selfish", which got me horrified enough to force myself to wake up, at 1:49 this time. And when I went back to sleep, I tried visualizing trying to comfort that poor kid and tell her everything would be okay, not that it would help. Oh, and in the dream, I had a celebrity death -- Kevin Smith, to be more precise.
So yeah. Bad night, very bad night. Good thing is that I have group therapy later on today so I can try and tell them what's been happening. I probably don't have to go into specifics, but I can say I've been having these nightmares and need to find ways to cope.
