비몽사몽

In the Korean comments

One top comment describes the performance with comic precision: in translation, “This seriously looks like me after getting an awkward three hours of sleep.” Another says, “So much white is showing that I thought he was actually asleep,” then calls him an 연기돌 (yeonggidol, “acting idol”), a playful blend praising how convincing the performance looks.

What the words mean

비몽사몽 (bimongsamong) literally describes being “not dreaming, yet seemingly dreaming.” Here it means being barely awake and groggy, a casual description that connects the title directly to the sleepless lyric.
