I have hyperphantasia, according to some crappy online test I took a few months ago.

It certainly has its advantages, like it occasionally combines with my relatively good memory for moments of photographic memory.
But it can also be somewhat depressing at times, like other people get excited to visit some castle or whatever and I'm just like "I've seen a castle before, I can just look at it in my head for the most part", which makes such trips significantly less interesting...
