What Christina said.

I also don't think they can put you in IP against your will if you only have a delusion that is not harmful to you or others. So you are fine even if the neighbor thing is a delusion unless you also plan to go attack the neighbor or you are so upset you are going to hurt yourself over the difficult thoughts. Getting in against your will isn't really easy if you are able to be articulate and state why you don't want to go in and how you can manage at home.
