I’m so confused by him

My so sleep talks but not often

He woke me up at 2am poking me in the back and talking and I said “what?” And he just.. wasn’t even saying words. It was just gibberish so I was like “WHAT?”

And he sighs like he’s frustrated and says.. the equivalent of “FIS THAWOFDWHFBEUWV”

And I was like “what in the actual fuck are you trying to say to me?”

And he gets so mad he puts his hands up and says “NOTHING” and rolls back over and mumbled “aaofbwiwgfjak”

And then I couldn’t go back to sleep.

So waking up for work today felt like death.

I asked him today what the fuck he was trying to say to me and he has no idea what I’m talking about.

Everyone’s like “what has your so said in his sleep that was funny?” And i can’t add anything because he doesn’t say actual words.
