Thanks a lot for your valuable comment as always.:)
Introspection is the first rule to start any digging work as Freud said.
Has an enigmatic answer I'll say that the introvert/extrovert question is just one because people interacting are just "one inter-experienced being" and that we must be prepared to deal with with the sensations and anxieties of communication that express our personality traits and "cracks".
We must learn how to compensate the exposure to opposite energies that are the same in essence.
I leave a quote for my next post:

"In the field of inter-experience between human beings, we must learn to put us in the place of the others to understand them and ourselves, because both peers permanent values are being virtualized in the process of communication, to improve our resilience for adaptation and the elasticity of our permanent values"- charlie777pt

We can't fight the "energy" of others "invading us", just look for the solution to contain it, in the dark corners of our mind.
