Reality & Illusion are a matter of perspective.
From the perspective of my sub-conscious id, my beliefs are real.
My opinions, my convictions, my anxieties, my worries, my problems, my pain & my fears are all real.
From the perspective of my conscious ego, only what I physically experience is real, the rest is an illusion.
Non physical reality is a projection of my creative imagination.
From the perspective of my super-conscious entity, physical reality is an illusion of my own creative imagination.
I am experiencing an illusion called reality and I am experiencing the reality of that illusion.
Reality is the experience of the present moment of here & now.
It is relative to space & time.
I am here in space, now in time, experiencing my own unique reality.
Everything else, past & future, is just an illusion created by space & time.
