In the practice of Lucid Dreaming one can wake up in a dream and realize how similar it is to so called physical reality. Many times I have become conscious inside a dream and suddenly woke up out of it through excitement only to realize I was in another dream which nearly fooled me once again like every other non-lucid dream does to every person alive.

Eventually it can be a seen that there is a definite possibility that physical reality is also a mental construct, in other words, the content of consciousness. This constant query as to whether this possibility is a fact becomes a prime focus that completely destroys the previous view of reality and what our true nature is, which is awareness itself.

Conscious awareness that projects content upon the screen of itself in a myriad of mental forms as in a dreamscape.

Just imagine you are in a dream and you are looking at your surroundings from inside your body through your eyes, hearing and seeing through the same senses as in your so called physical body. In the dream, all of these things may feel real but they don't exist. No body, eyes or any other sense apparatus, all imagination of a mind and it tricks you every single time you fall asleep and dream and you believe every second of it while you are asleep. This belief in the dreamscape reality happens every single night of our lives.You have to wake up to realize it is a dream. The same can happen in this physical reality which is just as much an illusion as the sleeping dreamstate.
