The most interesting thing for me with these dreams is the feelings I have when I wake up. I can still feel whatever the person was feeling and it's like I have that trauma even though it wasn't real. Unfortunately, they're usually fucked up. Some of them have stuck with me for years like they're memories now. I can remember crawling through that field but I know it wasn't real. It still makes me sick to think about crawling through the bodies. Most of my dreams aren't like that.
I've wondered if this is where some ancient beliefs come from. I feel like I was these people but not. I can see how people would have interpreted similar feelings as visions, reincarnation, other worlds, etc.
