My daughter hears dead people...?

Now I have no problem with this but my Husband is upset about me "encouraging" her. Here is a little backround: We live in my Grandmother's house as she has ped away and for years and years (before we even moved here) a little boy (approximately age 6) has been seen running down the hallway or in the bathroom. He appears briefly and wears a white shirt and beige "old time" knickers. When we moved here 2 years ago, there was no sign of him and being that I, myself, never saw him I was beginning to think he didn't exist. His handprint is in cement on the side of the house with his nam "Philip" and a box of his old baby shoes were found in the attic long ago when my grandmother was still very healthy and was cleaning out the attic (she threw the box away). Still, because I never saw him I was starting to think it was just an embelishment on my Grandmother and sister's part but then right after we moved in here my daughter started telling me she heard a little boy talking to her. She was 3 at the time so the way she described it was she heard the spider talking to her and she knew he was a boy because he had a boy voice. I got rid of the spider and ured her spiders cannot talk and dismissed the whole thing. Then several times after she would tell me she was hearing the boy voice again and he was asking her her name and if she would like to play. Sometimes she'd say he'd simply say "hi" and then nothing else. This always happened when I was busy cleaning etc and she was playing alone (I am a stay at home mom). As the incidences became more frequent, I became more interested and told her to talk back to him and that that would be ok. Well, when my Husband noticed she was talking about the little boy more and more he became quite annoyed and asked me not to discuss it with her at all and to tell her there is nothing there and not to talk about it. I just don't think this is right but don't want to cause too much conflict over such a supernatural issue. Marriage is hard enough as it is but I feel like I am taking something away from my daughter by denying her this could be "ability". Because she stopped responding to him the incidences have lessened quite a bit but just the other day he said "hi.......goodbye". For some reason that made me sad. My daughter is now 5 years old and she says sometimes she can feel him close to her or next to her. Any advice on how I could or should handle this...? Lastly , here is a video I took this past summer and I don't know if the little boy did this or if this doll I have is possessed. My son thinks it's the doll and he is the one who posted the video (he is really making a big deal about it and typed up the intro like he is me and everything..I was so annoyed) but I think it was the little boy. a href="http://www.youtube.com/watch?v=1nbr3jKVQlg" rel="nofollow"http://www.youtube.com/watch?v=1nbr3jKVQ…/a
