Hey I feel for you!!! I had/have severe nightmares, and night terrors (seeing a thing that wasn't a person). I also had the flashing eye problem!! My night terrors got so bad I had to sleep downstairs because I couldn't go upstairs. I would consider talking to somebody about your fears, worries, and concerns. That's helped with my nightmares and night terrors.

Also, it took a while for me to be ok with the night terror situation. Is there any loved one that might be watching over you? Once I found a way to justify that this thing following me and scaring me was a good thing, that made it easier to calm myself down and tell myself it's ok.

Hope this helped! ❤
