I know with absolute certainty that others don't see colors the way I do. The reason is my left and right eyes see color slightly but observably differently. If my two eyes don't even agree with each other, they can't possibly agree with the eyes of others.

Yes if fucking everyone started saying they can hear colors. Suddenly, half the population lacks a voice in their head or claims not to be able to imagine images.

Not being "neurotypical" whatever the fuck that means, has become SUPER trendy. Out of nowhere, suddenly everyone has a mental disorder.

I don't fucking buy it.

It's not a mental disorder. The brain is a very complex machine. It would be quite surprising if every brain would work exactly the same.

It's possible what people have talked about here is a pretty normal spectrum between the extremes of hyperphantasia and aphantasia. Especially aphantasia is not well researched yet.
