So your 'real self' fools others into thinking that your fictional characters are who you really are? (BTW, Robert deRopp, whom you seem to disklike, calls this 'the theater of the selves'.
All selves are real selves.
If you take the scenario away from human-to-human involvement, and replace this with, say, human-to-animal involvement then the 'all selves are real selves' proposition becomes more clear, imo.
If I would give two examples, then this might help.
1. 50 years ago I was a wildfowler. Wildfowl are canny creatures and would never let me approach them closely enough (by walking along a sea-wall, etc) to be in range. BUT, if I changed myself, and appeared as if to be working on the land, searching the ground for something, or raking the soil, I could get very close to them. As far as those ducks were concerned, they saw another me, a fake-me, a deception, but it was 'me' all the time.
2. Approaching an aggressive dog can be much safer if you (convincingly) appear as unperturbed and disinterested in it.
These simple examples are no different in human-human interaction, and a person can use scores of different 'selves' to cope with everyday life, just as animals can, by the way. We are everything that we are, in every way, and this can be found in animals as well.
The psycho-pundits probably need to spin this question beyond understanding because that is one of their selves, hoping to prove that they are very very profoundly wise and that we need to keep them in lots of funds, maybe?
And God, while existing in every part of everything, is disinterested in it all anyway...... but then, that's my Deism bouncing around.
