if your memory is non material dimension , no matter how many earths (planets) you rebirth upon, no planet is mother earth to you
the material dimension is where you are, never where you are from
but
where you are is where you belong because it is as much a part of the non material as the material dimension is a part of matter
the difference is , being non material, there is no matter so, instead of a location within a dimension as "home" (planet), the non material dimension it`self is home
