One of the strange cognitive things I have is to look right a something and not see it. I am searching for an object and it's right in front of me, but I look all over the immediate adjacent area (as on a sink counter) and cannot see it. This would usually be because there are other objects my brain is "cataloging", and misses the one I want. Sometimes I can only find it by slowing down deliberately, scanning each square inch of the are, and usually that way I can find it. When I belonged to an MS support group, this was one of the main neuro glitches people had. Very common.
It is not the same as seeing the object as something it isn't. It just is not there.

I understand those who don't want others to know about this. In the long run it will harm us to have some people know this. They will ultimately use it as an excuse to put us in a "home", if we live so long that a "home" is usual. I am afraid of this, because I don't like the food in assisted living places. They are not the Swank diet I am on and they would do the Swank very badly. I have been in a rehab twice due to injury, and they could NOT get my concepts on food at the first one, which was moderately priced: when I said I avoided soy, they refused to bring any bread which MIGHT have soy, even as a trace on a pan that baked the bread, so I was starving and losing weight, as the food was not very nutritious and I needed to eat all that was available, unlike at home. My soy problem was not an allergy, it's a sensitivity problem with Porphyria, which means a tiny amount would not overstress the Porphyrin system in my body, but no one came to discuss this. Then, at the other rehab I was in, it was a very expensive one, and covered by Medicare this time (or else I couldn't have been there) and at this place I COULD get my food needs pretty well addressed, good enough so I could live there. But Medicare does NOT cover long term care, and of course I couldn't have gotten LTC when younger due to my dx. I can't afford a good place.
