Eli5- how do people with aphantasia experience rem sleep, when they don’t have a mind’s eye?

Question

Is it still visual? If yes, how does one without the ability to visualize in their heads, visualize during the REM state?

Answer 1

My alphantasia limits my memory to mostly the outline shape, with only small color detail that is more a hint than reality. Faces are hard for me in particular, and I rely more on an outline shape and gait to identify people.

I rarely recall dreams. But when I do the its mostly shapes and suggestions or hypothesis of color and such.
