What a freaky night!

During the summer and weekends, I let my son sleep wherever he wants..the couch, the floor, down in the basement on the summertime bed, or in his own bed. Sometimes, we also sleep downstairs as it is cooler down there as well. On Wednesday night, he slept downstairs on the couch. It the middle of the night around 3:30, he comes up to me and tells me that the T.V is on. That is kind of crazy, I thought. Half asleep, I looked downstairs and sure enough the T.V. was on. I had him use the restroom. When we reached the bottom of the stairs, the T.V was off. I tucked him back in and went back upstairs. I was lying there in bed and I started imagining some creep downstairs. So I was so freaked out that I went back and got him and had him sleep in our bed the whole night. He and husband slept soundly...Me..not so much... Husband and I could not figure out how it turned on as the remote was on the end table and the timer was off as well.
