where in the heck are we ????

At a time when angels appear as demons and likewise the demons appear as angels
the question arises - " where in the heck are we? ".   I have developed somewhat of
a concern that we are currently living in a universe inside of a dead man's mind.

What are the implications of that ?  For example, should everyone in the universe
be collecting from the dead man's estate ?  If the dead man was in fact insane, what
does that mean for the universe's projected future ?

I hoped to come up with more information, data, and facts to determine if this might
be a justifiable concern. Facts ma'm just the facts.
