I'm like you. I have good spacial intelligence, but I never realized until reading this headline that some people actually see what they are imagining? That seems insane.
Yes. Most people do.

Think of a song you like. Play it in your head. Can you hear it? Can you tap the beat? Can you whistle along with the melody? Can you join in and sing the chorus when it comes? But you know you're not actually hearing the song, right?
Visualization is just like that, but for your vision, not your hearing. In the same way you can replay a sound you've heard in your head, most people can replay a thing they saw in their heads.
