That's what the 'No hay banda' stuff is for. When betty's dreaming, there are constant attempts by things to break into the dream and wake her up.

Hamlet's last words are 'The rest is silence'. That's what I meant about a classical ending and that's the kind of stuff that you would have expected John Carey to have remarked upon on Newsnight Review.
