If I think of tasting a lime, my mouth puckers and salivates like I’m about to eat something sour. I could probably say I’m imagining the taste, similar to how you described, like a 1/10.

I think hearing is maybe like that but like 1/100 instead of 1/10? It’s hardest to explain that one because with the stuck song thing, it’s there. I know it’s there. I can’t not imagine the song when it’s stuck. But I don’t “hear” it in any way like my ears hear things?

Smell I can’t imagine at all, but I can usually recognize smells (“usually” because for things that are similar to a memory, like someone wearing the aftershave my dad used as a kid or something that smells like my grandmother’s house from 25 years ago, are likely a miss, but normal things I recognize without question).

Visuals are probably more like smell in that I just don’t have them, but remembering visuals is more critical so I’m better at coping with that one.

I will mention I’ve met people and then instantly forgotten everything about how they looked, like I could only tell you gender and race, but I recognized them when I saw them again. Now, I had context clues. Like I met a couple in a dive shop in town then saw them at the airport on the way to the trip we were both going on through the dive shop. I knew I’d probably see them at the airport and I knew them when I did. But I couldn’t have told you a thing about them until then! It was the weirdest experience, and I think not being able to visualize was the root cause.
