Could somone tell me what this scene is about!

In Tyco castle Bartz is asleap shouts his name jumps out of bed and waves his arms while the others call him the weirdo

??/

i think i thought he was crazy or something

I'm guessing they were all up and then he falls off the bed doesn't he? I'mma guessing that the falling out of the bed was the cause of the name 'weirdo'.
