I genuinely can’t tell anymore, is it normal to be sensitive to noise while sleeping?

I am but I expect that's mainly due to it not being safe to sleep at night with an alcoholic father and co-dependent mother both being prone to rages and barging into sleeping children's bedrooms to punish them for whatever perceived offense the children have committed until I was left homeless in high school. Probably not helped by time in the military working a type of job with on call 24/7 waking up to deal with crises sort of aspect to the job. And then further impacted by time caring for medically fragile children. With a number of other trauma incidents thrown in for good measure. Even with a background noise generator (Insight Timer app) and listening to familiar audiobooks that don't rev my brain up, and like right now in the winter the sound of the pellet stove running pretty much 24/7- odd noises will wake me up. I also sometimes expeirence hypnogogic hallucinations and exploding head syndrome just for extra funsies. Can't use earplug because that just emphasizes the tinnitus. But yeah, I generally empathize with anyone who has a hard time getting a restful, restorative sleep.
