I just tried it and discovered that my memories consist mostly of still pictures and of movies that last for only a second. I can add sound, but it takes an effort to get sound and picture at the same time.
I conjured up my old high school (a facsimile above) and tried to remember what the students were like when sitting all together on the basketball court. I remember the boys punching each other on the arm til they were told to stop, and the general hub bub.
I was surprised to find that my memories weren't brightly colored. They came in desaturated tints, something like the picture above. If I focused on a color it brightened up, but when I turned my thoughts away again, it dimmed.
The memories were also pretty blurry. I couldn't make out the exact face and clothes of any one.
Come to think of it, they were VERY blurry. There were very few details....probably less than you see here (above).
The pictures didn't last long, either. I found that I couldn't keep a picture up to study it. My brain has no pause button. New pictures from different angles would appear, each with less fidelity to the original event than the first.
Of course I do vividly remember some details when I'm pressed (above).
Anyway, I believe the soupy memory was somewhat accurate, which is odd considering that the pictures were so fuzzy and ephemeral. Maybe the accuracy comes from something that was added to the pictures. Watching how the memory was constructed, I felt that a search had taken place, then a picture was put up, then a sort of emotional impression of the event was taken out of storage and combined with the picture.
Amazingly the non-visual, emotional impressions seemed to be the source for some of the movement I thought I saw. Sometimes I really didn't see that much movement in a single picture, I just strongly felt like I did.
Interesting, huh?
