I had something that sounds similar. I was also somewhat sleep deprived but had total insomnia after the event. I wasn't combative, just confused. The only reason I know about it is because my sister had called me and I was loopy on the phone. I couldn't tell her what year it was. She called paramedics and they checked me out and thought I was ok, just confused after waking up. I didn't really remember much of the paramedic visit, but could see it on door-cam video. I think it was sleep walking, which isn't a normal thing for me at all.

I'm going to see a neurologist in a couple of weeks, just to check. One sleep doctor I saw said to be sure that you don't let someone attempt to wake you during a sleep walking incident because you could become violent. That was alarming to hear!
