My BF is verbally abusive to me in his sleep. He often leaves the house in the middle of the night screaming. He says he doesn't remember. Now when he's awake he claims the house is haunted and he sees shadows. I'm really freaked out by his behavior?

I am being honest here.... Is he a meth user or ex meth user? Is he on any kind of new prescription drug? This could be a side effect and he needs to bring it to his doctors attention.

You should try to get him to see a doctor, or talk to one yourself if he won't.

Well there's three things he could be doing

1) Drugs

2) Having episodes caused by mental problems

3) Messing with you for whatever reason

All three of them require getting help, so act accordingly
