I have discovered in my quest for God that we are not a dream. Now with regard to your second point, I do concur; however, we are much more than an "attempt" by God to experience itself but are part of a perpetual motion machine, the universe, which does allow God to experience itself. It is an evolutionary process not just for us but for God as well. As we evolve towards God, God is evolving toward us.
We are immortal and we will always be immortal; however, our ability to live within an immortal society will not happen until we have developed the strength of character to do so. This is what we come to earth to do. Earth is a place where immortal (extremely technologically advanced) people come to learn how to be humane.
You are absolutely right; everything in the universe follows a path of logic. Nothing ever dies in this universe and neither do we and all of our experiences; including all of our love, go with us from this life to the next.
I appreciate your question and good luck in your immortal journey toward God-
