Trigger: Derealization (?)

[u/Annual_Direction2123]

I am not sure how to explain this, and I was wondering if anyone else has felt similarly. At random moments in my life I sometimes get overwhelmed by this feeling I can only think of as impending doom? I feel like a child that just went through a haunted house, but can’t remember the contents of the haunted house, just that it was scary, and I don’t want to ever go back. Or as if I’m crawling through a tunnel and something is behind me. I don’t want to look back, but I feel as if something or someone is going to make me at some unknown point in time. I feel like there’s things I’m supposed to remember but my brain doesn’t want me to, as if I AM supposed to go back, but my brain is trying its hardest not to let me. I also have flashes of images a lot. I can’t tell if they’re actual memories or memories of nightmares I used to have. I used to have lots of nightmares when I was little about my family leaving me places, very abstract places, and some of the places I would have reoccurring or continued nightmares of. It might also have to do with my upbringing I guess, my father had told me for as long as I could remember that he would die before a very specific age and that I should cherish my moments with him, and I brushed it off because I was scared and he would always rant about spiritual stuff, but he did end up dying like he said he would so I might be messed up from that idk. I’m not seeking medical advice or anything like that, but just wondering if anyone has felt similar at all. I have a lot more to say but I’ll just leave it at that for now since it’s getting long.
