When my son was young he was a prolific sleeptalker. The idea of recording him would have been a little weirdly obsessive, but the idea is a great one. The only ones I can remember were him sitting up straight, yelling "the button! the button! stop it!" And crying out "the stick keeps breaking, it keeps breaking. the stick. don't you see it, the stick," as I am saying "it's a dream, you're dreaming, there's no stick" and him saying "you don't see it, where is... i don't know... ... " I wish I remembered more, there were many nights of half sleepy talking shouting. Now he sleeps like a deadman.
