Uhhh this is so exagerated its ...crap. Sorry but I really don't get this one. 1 must sleep at some point or the person dies. plain and simple. 1 cannot cry and fill an entire castle until people drown. I mean, is this castle glass proof; no windows, no glass, no doors ? Do you know what kind of pressure it puts the window or doors when a room is filled with water. Medival construction wasn't really precise so water would come from every corner of a door and/or window very easily.
If I had a baby that didn't sleep like that would I go emo...nope. I would try lots of stuff to make him sleep but if nopthing worked...I wont force him to sleep. Is this a fantasy story with a morale...probably so but I never saw that.
