I'm not a psychologist, but in your professional opinion is it possible that you were hallucinating? Maybe the stress of the job triggered some mental issues that were dormant before?

Possibly one of the fey then. I haven't heard of any that have this description, though.

It's really interesting that your punches didn't work but the wrench did. Does the wrench have iron in it by chance? Iron is a weakness for certain entities. May give us a hint as to what it is.

What the heck do you do in that situation except run??

It's really weird that you were protected but not your family even though everyone salted. Were you using a different type of salt, like kosher, and they used iodized or something? Seems like the salt helped but why only you?

OP things do NOT move by themselves. That is not normal. Your parents know something, and they are gaslighting you. Try talking to your siblings.

I'm upset with the incompetence of the original police responders for not searching the attic when a kid, home alone, called about an intruder.

But why are they changing the time? It doesn't really benefit them.

OP, this is really important: do you remember turning onto this road? Try to remember. Was there a crash? I'm afraid you may be already dead and stuck in a loop. The only way to break out is to remember. It will be painful at first but it is the only way to break free.

Yeah I thought maybe the reason for the black bag was because the demon would appear as someone you love.
