The following written confession was shared via Reddit: So my daughter just turned 4 years old. About a year ago, she started talking about her friend "Eda" all of the time. I thought she was just playing and using her imagination. She never actually would play with the friend in front of anyone though.

These days the term “doppelgänger” is used to describe two different people who look unusually alike. The internet practically abounds with photos of identical-looking celebrities, people who’ve discovered their so-called doppelgänger in old artworks, and complete strangers who look like they could be long-lost twins.
