You woke up, sweating after a nightmare, you get up and think that you're just gonna go grab a glass of water, so you go to the kitchen, you heard some very quiet music before opening the kitchen door and once you walked in, you saw..your roommate, apparently dancing and really enjoying the music. After a few seconds of you staring, he notices and immediately stops dancing.

"Ah, hi there...what are you doing here ?" He mumbled, embarassed but also quite amused at you catching him dancing at 3am.
