A snake as a symbol of your (wake) consciousness in the religion of Ancient Egypt: https://www.youtube.com/shorts/SgUHvwQIYNA?feature=share Note, that even (spiritually) waking up in a new body after reincarnation does count here.
The ancient Egyptians tracked souls and found out that souls tend to stay together after reincarnation. The most prominent example might be the Osiris and Isis and Horus cluster or family. Looks like Kali is about that age in her current incarnation.
