When I was a kid, my mom used to tell me that I laughed in my sleep. I always thought it was weird and that she was making it up. Then, one morning when I was 22 or so, I woke myself up cracking up at whatever was going on in my dream. So apparently I do laugh in my sleep.
...So does Kairi.
(And for those wondering what on earth was going on in the background, it's the opening sequence to Rainbow Randolph's show on Death to Smoochy.)
