also you said you got the feeling of children. This might be something to talk about. Be careful with that though. You don't want to hit a nerve and get her angry. But if you can speak with her.. be nice to her. Speak out to nothing, just don't expect her to return with anything. I'm sure she'll hear you. Yeah if you could find someone, I'd try to go to them first. The Ouija Board... be very forewarned on that. That can get a lot worse of things. I really think you should just try to talk to her, and uncover the situation. At the very least, we people will be here to help analyze things along the way. I've made friends with some spirits. I can't speak to them directly, like some could... but I can sense their feelings.. (kinda like the TeleEmpath on Mutant X

) I think they hear our voices, they are just unable of responding back... through words like we speak. Chances are the home is just filled with memories and she doesn't want to leave yet. Gotta find some middle grounds with her, and help her adjust. Anything you find out.. report back! I'll help to the best of my ability.
oh and MSD.. Great Post!
