I do think you retain conscious awareness as you lose your physically manifested parts and depart this 3D paradigm/world. I also think you automatically gain expanded consciousness of everything you've ever become aware of, in any of your multidimensional selves. So this "remembering" will just be "knowing" because you've already taken steps to become conscious of it in some assemblage or format. And I think if you can relax infinitely enough, you may just be able to retain infinite knowledge in that expanded state.
