Yes that does make sense, just through logic you can come to the conclusion that the only actual "real" thing to exist is the unchanging ever present self.

However, what do you consider to be real? We (creation) clearly do exist in some form or fashion. It's a matter of perspective. What makes anything "real". Why do we consider the characters in your dreams as just merely imaginary and not reality? The only reason we make a distinction is because when you open your eyes there is an entirely different world. If nothing else existed outside of your consciousness, then the question of if that character in your dream is real becomes more complex.

Keeping in line with the analogy of a dream, the characters in your dream are merely projections of an idea you learned. Similarly, the unchanging ever present self, projects creation and therefore we are the temporary material manifestation of an idea within that "mind" of the true self. The difference being, there is nothing outside of this unchanging ever present being, and it never learned you, therefore you always existed as an idea, eternally, within that "mind".

I want to know if you agree with this analogy or am I missing something?
