Dreams

as your senses obtain information and send them to your brain(especially light) it wants to know what it all is. so as these brains experience other beings with similar structure it works together to describe what it has brought to its brain with something it can give through anything that they could obtain though its senses. over time this grew stronger and we developed a thorough communication.

we have developed an amazing second reality with our mind. one that you experience everynight. are you playing god as you create an entire reality.it wasn't real! no one else had seen what you had experienced. so if it wasn't part of reality. then this reality was merely a creation of your brain as it knows what things look like or feel like etc. it turns that into a reality that you believe to be true.
