Here's a part of a message I posted as a reply to someone and I wanted to give you incite into how names work. I live my life as close to the Arcturian lifestyle as I can right now. We all lead unique lives, but we cave common views on how things work. That being said, I posted this message from my viewpoint. Everyone has their own private reality, so feel free to adapt this to what you'd like it to be in your own reality.
I focus on knowing the world through the medium I know best, energy. I feel the energy of everything and I know what things do and who people are, because of their energy. I interpret the world through energy and Names signify the energy of that person. (Ex. Na'ven, my name, feels spiritual and like someone with advanced wisdom and someone who lives in harmony and balance. It describes me perfectly. I'm a 6D Arcturian (Our people live into the 9D density) and I live in harmony and balance. I bring as much of the feeling of home, to this world. I live as I feel comfortable.)
So, names are describing words for the person's energy, but to reference a person in 3D, you use a word. In the higher densities, you reference a person through energy, as its the universal language. When you picture something in your mind and you feel the energy of what you're feeling, do you describe it in full? No. You feel its energy and it plays off of your emotions. This is how you communicate in the higher densities. You think while directing you attention towards the person you're talking to. So, when you feel the person's energy, you know that person. You don't need a name, but in 3D, you think you do.
As for the name you think could have been yours at one point, it's yours now if you feel it resonates with you. =)
