Identity creation is the process of creating a new personal identity or alias for an existing person. You may have seen it in movies. The abused wife fakes her own death and starts over in a new town with new identity. A mob informant gets set up in the Witness Protection Program.
Someone steals your identity, wreaks havoc on your life and forces you to become someone else. Changing your identity and starting over is a common motif in books and movies and now in practical life. This has been a common way for criminals to start all over with a real new life. Some people especially women will get a new identity just to run away from abuse.
