Well that sounds terrible, so I'm really sorry for your experience with that. I have PTSD with knocking in the middle of the night, like loud knocking, and it doesn't even have to be in the middle of the night I guess, but so I get that to an extent. So I mean either just like a quieter, like a sing-songy alarm, or like getting an Apple Watch or something that will like buzz him and wake him up, but won't be loud and won't wake you up might be a good idea. I don't know.
