Real answer, in college the apartment I was living in was broken into by a neighbor and attacked my roommate. When I heard noise coming from his room I went to go check on him and the attacker turned on me and started to attack me. My injuries were far less severe from my roommate’s. Ever since then I can’t fall asleep unless I check all the doors to make sure they are locked even if I know it’s locked I’ll double check it before laying down for the night. At times when I’m alone in the house I can still get to sleep but it’s a restless sleep because of how uneasy I feel about being alone in a house at night. That shit sucks to never feel fully safe in your own home.
I do have those things and wish I could tell you that they do help. Fact is the feeling really doesn’t help or go away. The only thing that helps is not being home alone at night.
