When I was little child, I looked up from the bed out of the window. The view was a tall block of flats. I saw many hands, that waved behind the windows.
"Oh my God! Someone shut the people there and they are trying to call for help! Definitely I will see for a moment the silhouette of someone with a knife in his hand! But why are so many people there? Oh, maybe this is not some cult? Or there they are Satans!"
..It was just a tree branch in front of windows..
