Shadowsoul is right - though since I don't speak any German I have to take your word for it that this is an accurate translation. As long as that's the case, I agree with the synopsis completely. As for the who the sandman is and what he's doing in the song/video, I believe it has everything to do with the words of the chorus. "Sandman, sandman shut off the lights; The truth is horrible so send me a dream. Sandman, sandman come to me at my house; sprinkle sand in my eyes and never wake me again." The sandman is the anthropomorphic personification of sleep and dreams, just like Father Time and the Grim Reaper. So the singer is asking for the sandman to take let him sleep forever cause he doesn't like what he sees when he's awake, basically.
