I pretend my life is being livestreamed and narrate my own life
What makes you decide to pretend this is happening?
It gives me pleasure to know that I can live forever in my moments and thoughts and be watched and judged by the whole world.
That's certainly a unique way of living your life!  While I do find the action a bit strange, at least you're living your life in such a fashion that you'd be comfortable with others seeing how you act.  That's got to be a net positive!
There's always a chance that I do it for real and I walk around in my underwear with a camera on my stomach.
It is strange to pretend to be watched all the time but it is not hurting anybody. You should do what makes you happy.
