[Musicals] are they aware of the singing and dancing?

In musicals, protagonists don't seem to be aware they are doing something highly complicated and coordinated in their daily lives, with people they have never seen singing along and making the same moves. What's going on?

In the classic definition of musical, the characters don't know they're singing and the singing is used to advance the plot.  Whereas if you look at, for example, the Pitch Perfect movies, the music does neither of those things.  It's just characters singing.
