       Fun article about the brain and how illusions work.

       I did not read the article but will say that your brain is
       easily tricked visually
       I see crap all the time that isn't real as my brain tries to
       figure out what I'm looking at if I haven't seen it with one eye
       before.
       Leaves on an asphalt trail? Cobblestones.  Wrap on the bottom of
       a light post at Laurel Mountain?  A person.  A tallish boulder
       in dim light?  A person.  Dark asphalt repair on light asphalt?
       A hole in the ground.
       Mostly my brain's faulty decision making isn't dangerous but it
       has definitely freaked me out on occasion and can be painful if
       I miss a step that I didn't recognize or run off a trail because
       I didn't 'see' that it turned.
       I used to think illusions were cool.  Not so much any more.

       My husband has a somewhat similar experience.
       Only he calls them hallucinations including a couple times to
       doctors when I’ve been there. I can see the worried look on the
       doctors faces until he explains more and they tell him they are
       illusions not hallucinations.
       When his macular degeneration was diagnosed I finally realized
       at least some of this is caused by that. He doesn’t see some
       things in his visual field until he turns his head a bit.

       I call them eye glitches and occasionally hallucinations if I'm
       particularly frustrated.  They have made biking challenging.
       Strangely they rarely show up in driving.  But I don't talk
       about them much because I don't want anyone getting the bright
       idea that I'm a danger on the road.
