Active in daughter's bedroom

Tonight my oldest daughter went to bed as usual. She was up there for about a half hour or so and she came down and told us that someone/something was turning her door knob and opening the door slowly. I told her I would go up to check it out. While I was up there nothing happened. She went back to bed and she was almost asleep and her mother, who was in the bathroom at the time her a door knob turning and a door opening. She came out the abthroom and seen my daughter's door open once again. She asked our daughter if she opened the door and she said no and that she was almost asleep. So her mom had her come downstairs to sleep. She needed another cover because she was cold so I went back up to her room to get one. While  I was there I heard "get out". I still stood there and I heard "get out now". This happened about 4 times. Each time I was told this it was louder. Now, I consider that old stuff and for some reason it seems as if they are reverting to the old tactics and not the new ones they were previously doing for some unknown reason.
