I hate dreams/nightmares that portray me in scenarios or doing something that I would never do IRL. Like hurting a loved one. Or, reoccurring dreams about something that happened a long time ago that I'd rather not have in my head anymore. Move on already brain!
I heard a while ago that there are certain people who can control their own dreams, so even though I don't think I'll be ever able to do that completely I still strive for it. I try to remind myself in the dream that it's not reality. What goes on in my head when I'm asleep should be my property, not my minds concoction of what it wants to portray as reality. I have enough bs to deal with during the day and I don't want to be tortured during sleep too, which is really what it is
