Spirits:

The spirit that moved the knife isn't the same one I'm seeing right now. That one disappeared after Samhain.

how are you sure?

I can feel it. I could feel the energy of the spirit on Samhian with this one. I can generally feel the energy of a spirit if their not in an apparition form and there was no spiritual energy with this dog form that I could feel.

i dont know they do have ways of blocking the flow of energy

I don't think that generally happens though. I'm a medium so I can usually feel when they leave for a while.
