Old lady trouser-smell with yesterday's knickers

I do think that a lot of the 'black shadows' that people report may be an artifact of the brain and/or eye. Like I've said before, my migraines throw up 'black shapes', usually rectangular or square but sometimes just blobs - which must mean that the brain is causing them. So if there is a mechanism in the brain to create mysterious moving black shapes for migraine sufferers - just maybe it can throw them up at other times, even to people who don't suffer migraines.
