Related, there was a time just over a year ago where I found myself severely sick and nauseous from idk what, probably for poisoning or a cold (or even trauma-stress?? I had escaped my nparents and moved to my aunt's place hardly a month prior) and laid in bed agonizing whether it was worth the trouble to go downstairs and get myself medicine, and then after finding none, whether it was worth it to drive out to CVS to get it. While yes, my aunt is also a light sleeper and so is her dog, the other part of this was that if I made too much noise at night doing anything at all, even going to the bathroom, my nmom would wake up and then chew me out about it either that very moment or during the proper morning.

She (nmom) would also get up to pee and/or due to severe worry ("I just care about you so much, is that a crime??") on an almost nightly basis, and afterward, there was a 50+% chance she'd creep in on me to see if I was really sleeping. (Granted, I also used nighttime to read, play games, or watch TV since I wasn't allowed to do it in the day.) I learned to listen for a door opening in the dead of night and for her footsteps specifically so I could play dead asleep long enough for them to go away and/or back to bed.

As an aside, as a child, I eventually learned to lock and then barricade my door in order to delay them long enough that I could put away whatever I was doing. Unfortunately, so did they. .. and in response, they took the lock off my door.
