I can't remember the name of it, but I'll describe it the best I can. It was basically an old 6-8 minute cartoon about a little kid and his dog (or maybe it was a little kid and his/her sibling) who were dreaming about a strange fantasy world which started out alright, but quickly became a nightmare/bad dream. One scene that comes to mind is a blue creature with two heads that said repeatedly something along the lines of "Oogedy-Boogedy-Boo". I know I'm being very vague, but I don't remember much of it.
I'd appreciate it if someone could give me a link, or at least the name of it.
