imagination?

We were currently in the middle of quiet time when Wendell comes downstairs to inform me that a "person" is in his room. ???. He also said they came in through the wall. Hmmm...this is getting interesting. So I asked if he talked to them and he said no, they don't have a mouth. Hmff.. and then informed me that they are going around and around as he points to the ceiling fan in the living room and circles his little finger around in the air. I proceeded to ask what color were they but he didn't answer.. he just keep saying they were going around and around. I also asked if it was a bug and he said no, a "person". So, I thought I better escort him back to his room in which luckily, I did not find a mouthless person flying around in his room.
