A soul resembles a spark of light created by the collective consciousness to journey in many realities simultaneously to experience and learn. The universe in that sense is its university.
Reality is a computer generated consciousness hologram in which the characters it creates are programmed to believe it is real.
No matter where the soul experiences, its journey and programing (DNA in the physical), will always remain the same - to find its way home, back to source, origin, where it becomes whole once again.
