It doesn't matter. I personally don't have the capacity to create any false-selves I dream about anyway.
What false self is best? A pseudo-true self?
When I discovered that I probably was a narcissist, I fantasized about going to therapy and overcoming my narcissism and becoming open about my emotions and forming significant relationships and just becoming a happier and better person. Then I realized that it wasn't much different from how I fantasized about becoming a "whole new person" when I started college.
If you could actually attain this, well... I just don't see how you can pretend to reveal your true self without actually doing so. Wouldn't you (sub?)consciously know that something is wrong?
By the way, vertices, what happened to you that you're asking this?
