People can do very odd things and normal things - just depends on the sleepwalker. True meds can have an affect too. I have a history of sleep walking - only way I know is if there's evidence or if someone else in the house sees me. Last time I knew - I woke up in the morning and there were towels neatly place on the dresser and 2 night tables. Guess I went in the linen closet and did this.

People can do crazy things while sleep walking. My husband was very exhausted one night - he got up and peed in the corner of the room. Thank God we had tile and not carpet. I saw a mother on Oprah years ago - her teenage son was jogger - he got up at night and jogged down the middle of the freeway and unfortunately got hit by a truck. People have been known to venture outside and even drive a car. There's also sleeping eating where people eat very odd things - like raw meat and spoons of margarine. So people can do odd things. It sounds like you just had a very realistic dream.
