Ok, so I noticed that if I maintain my gaze on an object (not aggressively looking, simply observing) while sitting in semi-darkness (during the night, lights closed, room dimly lit by the outside lights), in a couple of seconds that object will fade away, literally, starting from the outside in, so to speak. I've tried this with various objects: a painting, my living room clock, the door, on different nights. I can maintain the focus as long as I want, and then just "will" the object back into existence when I'm done with it - or simply look away.
I had a lot of fun with this, demonstrated me just how fragile reality actually is...anyone else?

The truth...lies within.
