Seeing red

[bennyboy]

It does..you've clearly never tripped.......

I'm not talking about seeing a rainbow where there's no rainbow. I'm talking about colors that have no correlate in the real world. Have you experienced such a thing, say on LSD? I've experienced synethesia, but even then, sounds were represented in the normal ol' selection of colors.

You mean you've never seen trails that weren't -really- there......?   Or are you wondering why you don't have qualia about something that your visual apparatus would be incapable of perceiving.........?

The latter. Why wouldn't brain damage (or even just random brain fluctuations) cause the perception of real-world-impossible qualia, like colors that don't exist, or like flashes of another sense that humans don't have?

Hmmm. . . maybe it does, hey?
