I am because I say I am.
   If I'm not conscious and someone says I am, then I am.
   BUT if someone says "I'm not" and someone else says, "I am", the
   one that confirms my existence wins.
   Why?
   For me, there's no distinction between "imagination" and
   "reality" as the processes in our brains are real, measurable
   things in themselves and are part of the environment in which
   they find themselves.

   NOT seeing something that you say is real doesn't make it "not
   real".

   People might laugh, but that's a social thing, not a reality
   thing.
