Initially I probably didn't even call it acting, but dressing up or something. As a kid I think you fully imagine the world in which you want to inhabit, so you put some clothes on and just kind of freely imagine this world, and it's a total imaginary world. ↗
The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary. ↗
I spent my childhood in an imaginary world - probably because I needed an escape. I think that's one of the reasons people have imaginations - because they can't maintain existence here. ↗
