Hi and welcome Chi. I do see a couple of faces there. I can’t tell the context or lighting on the pics because they are enlarged. It could be a trick of the eye finding familiar images (paradolia), however when you add this to your recent activity it could be something. Here are the forums suggestions to try if you want to stop the activity.
Hi, Chi! I'm glad you found us! I have also experienced disturbed spirits when I lived on the third floor of an old Victorian house. The landlord decided to tear up the kitchen floor, and install new flooring. After that, I saw a ghost in one of the rooms. Needless to say, I moved out shortly afterward.
