Sleeptalker

The guy in the seat next to me is fast asleep... But he just started shouting " baby... Baby ... BABY!!!" and then he started groping around with his hands in the air... Then he started singing "na na NA NANA na NA!!" and slapping the compartment in front of him really hard... Then he started kicking stuff while still singing and snapping his fingers. Then he sat straight up in his seat with his finger in the air as if to make an important announcement... But the words that came out were total gibberish... He continued these activities for at least 5 minutes! I tried to record it... But it was too dark on the plane.
