Spirits and blessed objects

[Dog Guy]

So four of my friends recently moved into a house and including them and myself there has been about 8 people who have experienced either doors slamming, objects being moved to different rooms, lights being turned on, and someone knocking on the door or ringing the doorbell.
Everyone believes the spirit to be harmless but now my question is, if I were to take an object that has been blessed by a priest would the spirit take this as a threat and become hostile? My goal would be to just protect the house from any evil that's lingering around because no one minds the current spirit because it is not harming anyone.

I guess you can give it a (careful!) try. Perhaps leave the object somewhere close to the outside of the house, i.e. near the front door. In the worst case it then can be removed easily.
