In general, if I'm going to go somewhere, whether for business or pleasure, I prefer the trip to last long enough to remember well. Fly in, spend the day, and fly out just doesn't cut it much for me. I think that my ideal vacation that didn't involve visiting old friends would be an extended horseback trip into the Canadian wilderness, maybe to go fishing on a very remote lake. While the trip would be mostly a blur, I think that it would give enough time to retain some of the experience.
Not about aphantasia, but about prosopagnosia. This young man with prosopagnosia was taking his first parachute lesson and got visibly upset when the instructor said that you had better have your parachute deployed by the time you start to recognize people on the ground.
I first heard the term on a prosopagnosia mailing list a couple of years ago. Before that, it never occurred to me that there was a difference like this. My first thought was that of course I can visualize things. To me, visualizing a ship in the water was more of a knowing that it would be silly to find a ship not in the water (ignoring drydocks). It never occurred to me that people could actually see a ship in the water in their minds. Until tonight, I never even thought about about it also affecting things like sounds and smells. I can kind of "aurialize" sounds, but it is very faint and is of music such as The Sounds of Silence by Simon and Garfunkle, Yesterday by the Beatles, ... , and sometimes of voices. Even then, it doesn't really sound like I'm hearing it. As for smell, I sat back and thought about different smells such as cooking various foods and I get nothing. If I think of a hamburger cooking, the smell is probably the least thing that comes to mind. If I was cooking a hamburger and it didn't smell like a hamburger cooking, I would probably never notice the change.
