Sleep walking?

I didn't think I was going to post from Delaware, but the odd occurrences of the last half hour or so deem it worthwhile.

Ishmael and I were watching Ratatouille when apparently I turned around and belly flopped on him and told him "I'm gonna throw". He asked me if I wanted him to get me a bowl and I said "No, I want you get me some food". He stood up and walked into the kitchen and I apparently stayed on the couch and said "Hey, Ish." He responded "what?"; I told him that I loved him. After that I stood up from the couch and followed him into the kitchen. He asked me what I wanted, and I said "I want a new stomach". We explored food options. He tried out the bread that his sister gave us today and I took a bite of his slice; I informed him that I liked the bread; I wandered into the dining room and crawled under the table and curled up. Ish says that he walked into the dining room and asked if I was awake, and I did not respond. Whiler Ishmael was making the executive decision that we were eating pasta for dinner, I made the while sleeping decision to eat the leg of one of the dining room chairs...or at least to gnaw it a bit. Ish removed the chair from my mouth (thankfully!). Afterwards, I slept some more and
made sounds that indicated to Ishmael that I was probably in pain....

A bit later, I awoke under the dining room table, totally spooked, having no clue where I was or how I got there. The last thing I remembered doing when I woke up was watching Ratatouille. I have no recollection of any of the events inbetween. Apparently I appeared quite coherent during all of the interactions that happened between the couch and waking up under the table. Ish says my eyes were open and I appeared totally alert. Oh and when I woke up my stomach felt fine and I don't remember it hurting before I went to sleep either. Is it possible to sleep walk while appearing totally awake and coherently interacting with others? I am totally weirded out...
