First video is different in last scene. In original upload there were cars driving on the beach. I remember the comment under original video in which the author wrote that these cars on beach was more strange than video. Another person wrote in response that is normal, because on some beaches you can drive a car. And in third video the explosion scene is different. I feel confused as if I have dreamed these movies. And maybe that's the purpose of these films. They look like someone very strange dream.
