i have a lot of funny stories of my brother who's a bad sleeper.
one, we were camping a long time ago. i was 7 and he was 5. in the middle if the night he started saying "gimmy cooky gimmy cooky gimmy cooky" and started laughing. my mom said he couldn't have a cooky and my brother didn't answer. he has no memory of this.
two, i heard a scream from outside my door. i ran out to se my brother completly confused on the stairs and my mom at my door. my mom had asked what he was doing up so late, but he wasn't up. he was sleepwalking and my mom woke him up. she brought him back to bed and he passed out. he has no memory of this either.
three, a few days ago he had a night terror. a night terror is different than a nightmear. you are never dreaming when you have a night terror, but you scream and kick and punch the air as if someone was trying to kill you. so my brother woke up everyone in the house screaming like crazy, and he has no idea it ever happened.
as for me, i sleep soundly.
