What is Reality, Really?

Reality is a concept, a social construct, a figment of the human imagination, a fleeting dream, or a never-ending nightmare. We can't quite put our finger on it.

Some say it's the sum of all our collective experiences, a tapestry of memories, and the culmination of all our hopes and fears.

Others say it's just a simulation created by a bored teenager in 2008 to keep us entertained while he was trying to finish his calculus homework.
