It could be any number of things or traits.
From blood type to viruses you’ve had (eg cold sores, Ross river ect) to the density of your bone structure or DNA.
They could also factor in the type of personality you have. Are you shy, compassionate, confident, a bully, a leader or a follower, are you in tune
with your energy and of others, are you a sensitive or psychic. Are you shallow or egotistical by nature?
It would be good to compare these traits with people who have had encounters.
