<human>: Let's start this story out with the fact that I have episodes where I sleepwalk. It's not very frequent, but when it does, it's more of an "oh look, it happened." Sometimes, I end up roaming to the first floor of the house and settle down on the couch. It started in kindergarten, and my parents witnessed me walked around like a drone. Now that it's happened a few times, my parents have taken the opportunity of making fun of it sometimes, like if something is missing, they ask "did you "dreamwalk" again?" (what I called it when I was 5)

Well, flash forward many years later, and I have a little brother who is now 6. The sleepwalking episodes have been rare, but we've never told him about it. 2 days ago, I didn't get any sleep, fixing my phone because it crashed and I lost EVERYTHING (an online backup saved the day.) However, because I pulled an all-nighter, I was exhausted. So I decided to turn in early. (9:00 PM) Apparently around 10:00 PM, my little brother snuck downstairs to go enjoy himself some late night Cheetos. He sat on the stairs and was munching away happily, as quietly as he could. About then, I had started sleepwalking, because the next thing I knew, I woke up at the foot of the stairs with my brother screaming and my parents trying to comfort him.

In my sleep, I had managed to fall down the stairs and scare the living daylights out of my brother because we never told him that I did this, and he thought I had been killed as a punishment for stealing Cheetos.

Could you distill the essence of the text into 1-3 sentences?
<bot>: 6 year old steals Cheetos. Witnesses unconscious brother fall down stairs. Thinks I'm dead because the karma gods love Cheetos.
