I am 74 years old and I experienced sleepwalking last night for the first time. Is this dangerous?

I just seemed to be making a sandwich for a snack whics I do quite a bit. Next, I was sitting at my favorite chair. I had made a sandwich with just a thick layer of pepper on the bread. I went and spread er over the pepper. I ate half of the sandwich and my two dogs ate the other half. It was hot and I knew it was pepper.My next waking moment I woke up in the upstairs bed which I seldom do. I don't remember going upstairs. When I got down I looked where I made the sandwich and pepper was spilled all around and the er dish had the pepper spots left by the knife.
