This emoji is often used metaphorically beyond just the weather. It can refer to digital data, as in "cloud computing," or express a state where one's mind is clouded with complex thoughts.

Just as having a "head in the clouds" describes a dazed state from overthinking, this emoji often cutely represents being lost in quirky daydreams or fantasies. This makes it a witty emoji to use when you've momentarily drifted off during a conversation with a friend.
