Googley, what kind of doors are they? I have a regular door, with a deadbolt, and a sliding door. I put a metal bar in the sliding door and hang my keys on my deadbolt (so if it opens, they will crash to the floor). Maybe rigging something like this will help? In old apartments, I was known to put chairs in front of doors, or cans, lol.

Waking up from nightmares is horrible. I am sorry you are stuck dealing with this
