I’m pretty sure I have this. How did you find out?
Not being able to visualize anything, all of this fell very flat. It wasn’t until later I found out there actually are people who can visualize things as if they were happening. I have trouble wrapping my mind around what that must be like, but I bet all these visualization exercises make a lot more sense.
Outside of that, the whole visualization to practice idea rarely does anything for me. (I still use the term visualization even now that I've discovered it doesn't mean for most others what it did for me!)
