Okay, here's the thing. I have flashbacks that really DO come out of nowhere. There's no recognizable trigger for it. It leads to me feeling trapped, and I see stuff on my arms/ they go numb, and there's no trigger for it. It's happened in the hallway at school, it happens when I'm in my bed, it happens when I'm with my family watching T.V. It's really, really odd. If I don't have triggers.. Then how can it be a flashback? I know it is though. How can I figure out the triggers? It happens sporadically, suddenly and I can't track it. That's another part of the reason why it's so frightening. Can someone explain it to me? How I can figure out what triggers it or if I'm just doomed to flashbacks which appear out of nowhere?
