at the carnival 

describes a state of mind when you're completely out of it.
or when you are super tired and feel like you are going to die.
being at the carnival can be caused by dehydration, too much partying, not enough sleep, too much stress, or when you're just completely out of it and etc.

Leah: hey what's wrong?
Devon: nothing, i'm just at the carnival. i was up till 3 writing a paper last night.

or while outside of baskin robins, you can wake up and say
'are we at the carnival?'
and leah, eric, sam, melissa, and vanessa will reply: no, that's just the carwash sound.
