On a number of occasions, yes. I simulate difficult arguments as a means of preparing myself, and also satisfying my appetite for quarrel. Like writing a thorough letter designated to the nearest trashbin. I also simulate conversations centered around my success. Victories to come, victories that's never meant to be. I've heard that imagining scenarios gives the brain the same effect as if you actually lived it. You just don't get the lingering feeling of satisfaction, or despair, whichever general feeling the given scenario results in. This is useful to me when simulating my success, as in my fantasy I take my credit due happily. In reality I scoff it off and take no pride unless my peer(s) forces it on me. I honestly don't know if I'm being modest or pathetic.
I can also be goofy with myself on occasion. Tell jokes and do silly gestures to nobody, and I usually laugh. Encore!
>I always imagine people (...) I wish to be with (waifu, etc) with me. I tell them what time it is every 30 minutes, I talk about what is on my mind and often explain the situation.
I.. why have I never? It sounds pleasant divine, but entertaining it too far and I stir a wave, black and inbound. It chips away at my sanity, and like motoric reflex - I pull out, shut the door - nobody home. Baby go away, haunt my domain no more. You're just a ghost, a beautiful ghost.
