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.
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.
When your eyes view your physical surroundings, they look for boundaries to define things. This is not a flaw. It’s part of the Earthly construct; a collective assumption that supports the theme of separation. It's for your growth, and you chose it!
