i was trying to fall asleep and all of a sudden my room got below freezing and my window opened and so did my closet they then close quickly in like 2 minutes and everything goes back to normal. my sister then comes into my room pale. the attic door opened and the window opened in her room and it was also below freezing. we told our parents but they never believed us. this went on for about 6 days and then it stopped all of a sudden. this happened about a month ago. then it did it again last night but this time the light turned on and it was flickering. the room then kept changing from hot to cold. this time it last about 5 minutes. our mom now believes us because it happened in her room. but my step-dad wasn't home he was on the road.
