I believe everytime you go to sleep you enter the world that you will be when you die. That is your real world. You enter the physical world without memory of who or what you are. You don't remember your power to create your own reality. You keep those memories or the knowledge of who you are hidden so everything in the physical world is new and exciting when you experience it. You need to sleep to visit your real world to map out your plans for the next day, week, month, etc. when you return to your physical body. This life is only a game. We are only a thought created by ourselves, so when you die, there are no answers to learn. You already have them but have no knowledge of them while you are here. I wrote a hub about this called "Gods Creation Could Be your Own", and also a poem in another hub called "I Am My Dtream Of Life". I think you might find them interesting.
I enjoyed your question and it does give us all a lot to think about. I don't know for sure if I am right in my thinking but it is a concept that I believe in.
