One of the biggest challenges in the release of your fourth dimensional world, is your belief that the physical environment around you is objective. You believe that all of those physical things existed before you came along, and will exist in the same form after you die.
Your physical world has a multitude of events and situations occurring on many levels. Your five senses pick up a very small percentage of them. When you go out on your street, you focus on a very narrow range of events.
Here where I am, we can have bodies if we choose to, or we can express purely from the ethers. I myself do have a body, which looks quite similar to humans in most ways...except for the tiny feathers on my face, that is.
