Can you "get to know"/be friends with parts of the house that are especially scary during the daytime and have "them" help you when it's dark? I would name doors or windows, make them "pets" and either go out to dinner occasionally with someone or have them in until 9-10:00, get some "life" into the place. During the day, stand where you see the man standing and then look there at night. "Memorize" the stairs and make them "yours" so no one "else" can claim them.

I found that when I didn't go out or have any "real" interactions during a day, that night I had worse trouble than usual. Now I try to go out shopping or to the library, talk to clerks or neighbors, someone -- have a small "goal"/thing to do each day out.
