New home, what's going on here?

Hi Mic....welcome to the forum. Those scratches look pretty serious. Is this the inside of the kids bedroom door....so door leads to hallway? The last time I saw scratches like this in any paranormal situation it involved a clients dog. The dog was so spooked by what was inside the house, it would claw at the doors as if trying to get out. Were there any items at all left in the house when you moved? Antiques, personal items or anything out of the ordinary? Do your best to start off with logical thinking. Try your best to debunk odd things that happen. When you come up with nothing start a journal and take notes of anything weird that happens. Younger children are definitely more open as far as being able to experience things.
 
you can check it by yourself with vibration technique from your hand to ensure if it is from real animal or spirits around your house
