How is the word doppelganger used in vernacular?

The word "doppelganger" is often used in vernacular to describe a person who looks strikingly similar to another person, even if they are not related. It can be used in both a literal and figurative sense.

Here are some ways it's used in vernacular:

Literal sense:

* "I saw someone at the coffee shop today who was the doppelganger of my old college roommate."

* "The new student in class is the doppelganger of my brother."

Figurative sense:

* "This new restaurant feels like the doppelganger of the one that closed down last year."

* "The city's new mayor seems to be the doppelganger of the old one, with the same policies and ideas."

Common phrases:

* "Meet my doppelganger." (Used humorously when two people look very similar)

* "That's my doppelganger!" (Used when someone sees someone who looks strikingly similar to them)

Note: The word "doppelganger" often implies a sense of eeriness or mystery. It's not just about someone looking like another; it's about the unsettling feeling that there's something more to it than just a resemblance.
