oh shit doing that got me in soo much shit when i was in high school. the problem is that i would sit up and have my eyes open but still be a sleep. sleep walking and talking is common with me and my brothers. my mom would ask me to do chores or pick up something and she would think i was awake but nope i was dead asleep.
never slept walked but yupp lol i would get a phone call later in the day and my dad would ask if finished what he ask.... i would always say no not yet once i finish doing "whatever" i'll finish... then he would finish my sentence. worked well
