Have you seen the movie that its producer termed "The world's dullest film"? Called Baa Baa Land it shows sheep standing in fields and is eight hours long. It's supposed to help you relax.
Now, I've nothing against sheep. Peaceful, woolly little fellows. But I don't think I could watch them for that length of time and I don't expect it would make me relaxed if I did. But who knows? For some it may be just what the doctor ordered.
