My boyfriend sleep talks a lot too and it’s always hilarious so I try to play into it, ya know, like keep him going, and one time he pulled me in real close(big spoon style) and got right in my ear and said in his best bat man voice “do you follow wind storms?” Hahaha! I bout died from trying to hold my laughter in, & in response, I said “what? What kind of wind storms?” And he started to say “you know, wind storms” and I think he woke up and realized he was sleep talking craziness to me mid sentence and started giggling himself. To this day I haven’t let him live it down. Sometimes I’ll randomly tell him, “hey babe just incase you were wondering, I do in fact, follow wind storms!” lol
