Reality Illusion

So again with the Reality Illusion. I’m presently working on Rear Window. The Reality Illusion has come and gone a couple of times at this point and I was starting to be concerned that it had gone for good. But I was working on the window frames (just cleaning them up a little) and I darkened the windows themselves.  The Reality Illusion showed up suddenly all over the painting, not just on the windows. When I say ‘suddenly’ I mean the next day at the beginning of the next painting session. I don’t understand how this works but I can twist my regular theory to explain it somewhat. The truth is ‘I don’t understand it’ but I like to tell people that I do because I like it and believe that people think an artist should know.
