Is it normal that i do these things when i sleepwalk?

I sleepwalk regularly on a nightly basis and a I do rather odd things when I sleepwalk.
I do like four things, the basic walking around, I go into my roommate(s) room(s) and curl up on their beds and talk, I sleep-eat, and on the rare occasion I soil myself.

One time I woke up and there was a peanut butter jelly sandwich half-eaten and stuck to my face, and I don't like jelly. My girlfriend (she shares a room with me) told me that she saw me get up and jog to the kitchen and come back with a sandwich, which I don't remember doing.
Another time I woke up and I was spooning my roommate (male best friend) in his room. I was confused and he didn't know I was there.
What's really annoying is that sometimes I go sit on the toilet and take a shit, only I don't pull down my pants, I just poop in my drawers. I've poo'd myself twice that way.
The most odd occasion was once I woke up, and my pillowcase was full of food and household items. One of my roomies heard the ruckus and filmed me, I was raiding the fridge, and I put it all in a pillowcase. I just took forks, syrup, corn casserole, bread, pickles, just put it all in a pillowcase.
Another thing relating to me poopin' my pants is that I just kinda shat the bed, I woke up with feces in my pants. It stunk too. My girlfriend forgave me. :3
One time it appeared that I was praying, I woke up on my knees with my hands clasped together and I'm a strong atheist.

Is it normal that I do some rather odd things when I sleepwalk? Danke.
