I have spoken aloud, but not directly to her except to ask what her name might be. I cannot communicate very easily with spirits; I can feel them, nothing more, so I'm afraid that anything I said wouldn't be returned, or at least I wouldn't understand the response.

Do you think if I made a little playhouse like thing (no bigger than like a bird house or something?) and offered it to her, she might take to it at night?

One of my theories is that SHE is scared of whatever my uncle saw outside, and so she woke him up, and he saw it too, and it scared him.
