@John Naylor my experience is indeed very similar.
Exactly. From hearing my friends and people on this thread who do not have this 'problem', it appears to be very weird for them not being able to that and still 'remember' things. I believe our minds are just wired differently and is more based on a list of facts and associated emotions. I too have to interact quite some time with somebody until I have a list of features that I can assign to each of them. Doesn't mean I don't recognize them, just if the interaction was brief, I don't have enough info to identify/name them.
I can hear that too, it is just the visual aspect that is not there.
I've been practising since a week of two to try to get more visualizations and just before I fall to sleep, I seem to be able to do it sometimes. I do dream vividly.
