^ didnt let me edit........I'll be staring at a wall, and I can see the patterns of the wall changing and shifting depending what part I concentrate on. Then I imagine the wall is expanding and contrasting with my breathing, and I see it bend and warp slightly. Also if I stare at somthing and imagine that it has dissapeared, it will fade out and be replaced by static fuzziness. Its really very interesting, I think I would miss it if it was gone.
