You are not mentally ill. We have the ability to have more than one identity/ego in our heads. It's only a problem when it's damaging to you/your life.

You can also have no ego/identity, which is the holy grail of many religions/philosophies.

Lately some communities have formed around creating additional identities personified as fantastic beings they call tulpas. Some of the people there can even see/perceive those identities.

Managing our egos/identities is a very powerful tool.
