The article is only about the absence of mental images, but the same is true for all other senses as well. People might be able to recall or imagine images, sounds, smells, tastes, feels while being awake or not. And it can be in all permutations, tho, vision affected seems to be quite common.

the only internal sense I have is my own voice. I cant even "imagine" music but rather hum it in my own voice at best. Same with others' voices

		Interesting. I can replay or simulate other people's voices (real people, obv) and can 'hear' music I know by replaying it in my mind. Of course, not perfectly if I forget the words, it might fill in with some tum-te-tum, or only recall a fragment, but it's usually playing as at source. Makes earworms very annoying, of course.

		Ditto! I tend to hear my internal voice beat-boxing music rather than humming it, though...
