Reality is a figment of one's imagination, caught up in the nightmare of the dream of time.
Mathematicians and physicists have long held that we exist within a reality of four dimensions, three dimensions defining space and the fourth dimension defined by time. Within our reality as we define it, things only exist in reality at a certain point in time. We live within a reality defined by time. Then we are but a dream created by one's self. Then everything is a figment of one's imagination.
