The past doesn’t exist because it’s already gone. The future doesn’t exist because it hasn’t arrived.  The present becomes the past instantaneously. Therefore I believe we all live in a dream. Some are shackled by the dream of the past.  Some are harnessed to the dream of the future. We are all being spun like a dreidel by the whirlwind of fabric that constitutes the coming and passing of time.  Your dream, your choice.
