I wonder if folks with aphantasia can dream. If they can, it should be pretty easy to imagine objects. But then again, I am not a neuro-scientist
I can dream perfectly vividly, but cannot visualize anything when awake. I’m on the more extreme side — I can’t summon forth any imagery, which is unfortunate for me because I can’t even remember family, friends, or my spouse’s face beyond rote list of details.
