Blessings
So I had to bless the object that entered my home to stop the knocking. I find it funny how things seem to hold the past feeling of the previous owner. I just think it may have been a child playing.
I did not feel any negativity coming from it and I pretty sure if there were the objects in my home would let me know. They tend to move. Example I have a plate that has two koi fish in a pond on it. The last time something negative happened in my home the plate would not stay right side up. It would always be upside down.
Since that has not occurred than I feel confident that every thing is right as rain in my home for now. At least with the spirit would.
I wish you sweet blessing for now.
