Who said anything about fear?
The Doppelgänger phenomena is real. There are a few of us on this forum that have either seen or are aware they have a Doppelganger. I'm one of them that is aware there is another that looks just like me, has my memories, knows my friends, and could just drop in and replace me and no one would be the wiser. There doesn't seem to be a why or how this could be. I have several theories. Also just a s wild as the phenomena. I know Bajak and Gibbs have talked about actually meeting their Doppelganger.
