when i was little, my big brother alex used to play a game with me and my sister called monsters.
alex would put his duvet over himself and pretend to be a monster and me and my sister would have to push him off his bed before he ate us (or dragged us under the duvet with him!)
when we finally managed to push him off the bed, he would take the duvet off and hit the wall without us knowing to make it sound like a load of monsters were coming in the direction of his bedroom. and we would always get really, really scared!!
