Hi guys, I am new to this forum! I want to talk about something strange that happens around the office where I work in at school. So I teach children during the day and adults in the evening. Last year I noticed strange shaking on my office door and chairs that would occasionally move a few inches by themselves. So after this carried on for a few months I set my IPad up in the corner of the room and left it on all night plugged in recording my office using an App. In the morning I looked at the forage and saw a strange black shape walk past the door. The time that the black shape was seen was at 10:23 at night and nobody would have been at school at that time. The school where I work dates back to the 1800s and has seen quite a lot of History. What do you guys think ? P.S I have my own Podcast about people with paranormal stories.
