Someone who is possessed is thought to be controlled by an evil spirit. It is being used as a joke here, as the children are going crazy and Dr. Strange assumes they are under control, but really they are just behaving like children. Ex: What possessed you to do that? Ex: I felt like I was possessed by someone else. I was out of control.
