How it's used

The inclusion of 晒 acts as an intensifier, emphasizing that the person is completely zoned out or entirely blank. It carries a slightly informal or critical tone, often implying that the person should be focusing on something else instead of daydreaming. It is most commonly used when someone is visibly staring into space or failing to respond to their surroundings.
