'People make it sound like they are able to see the same with their eyes closed as they can see with their eyes open.'

It's a spectrum of vividness. At one extreme, a few per cent of people are classified as aphantasics. At the other extreme, people have a photo realistic mind's eye. Most people sit somewhere inbetween.

I don't think people are necessarily overestimating. Some people just imagine the world very clearly.

I would say that I can see objects in my mind with something close to photo realism. The only time that things become hazy is if I imagine the entire city in which I live. I fly round imagining every street and I can see familiar areas very clearly, but if I stop and examine a street I don't know so well, I can't remember which exact shop is where. But that seems to be a problem of memory, not visualisation.
