I can't tell you the number of times I've been dreaming and I've killed someone, or maybe I had a kid, or I had to get a leg amputated, something that's a lifechanging event, and I'm always thinking, "I've really fucked up now, my life is ruined" and then I wake up and I'm so relieved. I have these sort of dreams all the time and they are very lifelike, especially the ones where I kill someone.

But what do I think dreams are? What I read somewhere(yes I can read, I read the post title didn't I?), is that dreams are made from different still images which your brain puts together like like a storyboard, then your tries to "animate" the story by filling in the rest.
