I don’t think this is a symptom. I’ve genuinely had weird experiences and I live in a sketchy neighborhood. I mean not that long ago I was sexually assaulted around here.
This might seem like a weird thing, but I remember someone a while back being afraid of people breaking into their house. Their solution was to put a piece of clear tape across the frame of all windows and doors on the inside. That way, if someone opened it, the tape would be broken. If nobody did, the tape would be in place and they could reassure themselves that it was a delusion. For the door they entered and exited from, the tape would go somewhere hard to notice on the outside.
Gosh, that is for sure me right now also. Not very fun. I hope you can get some consistent and reasonable sleep soon. Do you have any tricks that usually work for you?
