Entities that visit your home before an investigation

This green slimy entity always visits me before I go to the sallie house. I don’t know why. It is always in my back yard never in the house. I think I have too many wards up inside. But this is my first clue that the house knows I’m coming. I know that sounds strange but that’s how it feels. Have any of you ever seen something at your homes before an investigation or a live show? I’d be interested to know. Or how about stranger happenings after watching a live? I had to have two cleansings after this latest lives. It’s been years that this entity has visited me before a trip to the sallie house.
