In trans communities there’s a team “going stealth” which generally means when you’ve reached a level of presentation that people can’t tell you’re trans unless you tell them.

I coined the term “going ghost” to mean when ALL your professional and governmental documentation has been changed to reflect your true identity - both name and sex

I myself have gone ghost, I’ve either actively erased or mentally suppressed most if not all aspects of my past self. To be fair, the last time that person existed was over a decade ago.
