I don't know if most people do, but it's a regular experience for me. Honestly if it wasn't for the screaming I would probably still be undiagnosed. I knew I had been through trauma but I was very good at ignoring, avoiding, and stuffing my feelings, even during triggers. I genuinely thought I was fine. Then I went to college and freaked out my roommates enough times with the frequent screaming I started to wonder if there was maybe something wrong. To this day, the screaming is one thing I can understand as a sign I'm treating my emotions in an unhealthy way.
Side story: one time I went to a girls camp and woke up 20+ strangers, in a cabin in the woods, in the middle of the night when I woke up screaming. That one I can laugh about now but I was mortified at the time. ?
