A Horrifying Night

One dark night I was alone in my home went to bed at 11:00 and as soon I laid my back in the bed the light started to get off and on. I was so terrified and then I got up and the light stopped I was so scared that I did not sleep the whole night and went to the hall and started to watch TV and the next morning when my parents came back they were shocked to see that I was lying on the sofa ...They asked me why did I sleep in the sofa and I replied them what had happened so they went to inspect the room and they couldn't find anything then they asked me in detail what had happened so I showed them and when I lied the light again started blinking and then we came to know that it was just the remote of the light...It started blinking as when I lied on it the button was getting pressed and then I got relieved...I wonder what would happen if my parents wouldn't come...
