My husband, very early in our relationship and normally casual or just physical or fun about initiating (when awake) said in a loud, mechanical, monotone, commanding and way-deeper-than-usual voice “Quitate la ropa - ya es hora!” (Take off your clothes!! It’s time!) And proceeded to pull my clothes and grab me in a really uncharacteristic way. I thought he was joking around. Turns out he has sexsomnia. I had no idea this was a thing until I did some internet searching. Variations of this have occurred periodically ever since. Our sleep doctor said he had only read about this condition - it’s kind of rare (and sometimes fun). But creepy because he doesn’t remember the next day.
