Infinite mental regression could be observers of observers of
   observers, or it could be the infinite mirror optical illusion
   but bouncing around the six-second phonological loop, home of
   jingles, ear-worms and every song that gets stuck in your head.

   I conceptualize it as overlapping personalities based upon every
   person you've ever known, real or fiction - it's all fictional
   (since we only know of a person what they show and how we
   perceive - ie - a fiction-based-loosely-on-reality).

   Helps me sort out my thoughts sometimes. "it's YOU AGAIN,
   mean-girl from when I was 8 year old. Why are you talking with a
   deep male demon voice? Begone, little witch!" and head clears
   up. :P

   You're not crazy. We all have voices. Some are worth listening
   to. Some are worth ignoring.
