I use to pretend i was Malcmon from malcom in the middle.
So everytime something of interest would happen I would turn around, look over my back at the "camera" and talk to my audience, breaking the 4th wall. Then I would turn around and jump back into the show continuing a friendly discussion or playing lego etc..
I still do similar things today, it helps to believe im being watched because "being observed" is a strong mental state to be in, it forces us to take full control of our actions and what we do.
A funny thing i use to do is pretend there was a 3rd person in the room with us when playing music. We use to sometimes rap for a cringey joke. And id imagine eminem was in the room with us as a 3rd person - i try to imagine what he would say to me If he was here to improve or get better. I dunno..
short answer... YEES and im not religious.
