Identity are just the memes you have come to acknowledge as being the “individual” you believe you are. That energy is reflected onto others so in a way they can also “see” what you see, but at the same time they “see” what you don’t see in yourself. This is where the mind plays tricks on people, and has them assume they are “other” things. Like bouts of insecurity for example.
They are and they are not you, you are ONE connected with the source that is the everlasting infinity of all this.
Basically you get all these memes from construct definitions of culture.
A person has 3 faces according to the Japanese:

2- The one you show friends/family
3- The one only you know
You are sad, but why are you sad? Petty things of this world don’t really matter in the long run, I mean, there are infinite amount of universes coexisting with ours, we are less than a grain of sand in the spec of everything.
