Sleep-Walking?

HOLAH!!!!!!!!! Well!!!! This happened about two years ago... [I can't believe that I still remember this!] Two years ago I had a bunk-bed. So I was on the top-bunk that night, remember that, TOP-BUNK!!!! And I fell asleep on the top-bunk... The next morning I found myself in my mom and dad's bed!!!!! [My dad was in the middle!!!!!!] I took my dad's spot and he was sleeping in the middle!!!
So... obviously, I slept walked. No doubt about it!! But how could I have gotten down from the TOP-BUNK???? Climbed down the ladder, right? BUT, I was asleep!!
Anyway!!!
POST YA GUYS LATER!!!!!
