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

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

REM sleep doesn’t require visualization. People born blind experience REM sleep just fine after all. 

As for how we dream/visualize, well I can’t speak for others but for me, I simply remember the experience the same way I do a previous day.  I can’t “picture” it like replaying a movie and watching it but I can remember details like some of what was said, what generally happened, where things were relative to each other.  

For example I know a red car was red, just like I can remember seeing a red car yesterday. The information is there it’s just not stored as images.  

What I can’t understand is how people who DONT have aphantasia differentiate reality from fantasy if they are seeing both when they “imagine” things.
