When I first read this, I wondered if you sleep walk, and are actually doing these things while you are asleep.

On the other hand, even skeptic that I am about these things...things happened in the house I grew up in. Little things that we didn't even tell each other about, just saw/heard them as odd things and moved on with our day. It wasn't until years later, after I had moved out, that something a little bigger happened, that we talked about the things we had each experienced (and they were few and far between) over the years.

Anyway, after that, I did read that you can write a note, and put it in plain view. In the note, tell the "spirit" there that it is time to move on, they should no longer be here, etc. It's been awhile since I found this, but I think the reason for the letter was that "spirits" cannot hear us (and maybe not see us?), but they do see the house, room, etc. , so will see the note.
