While discussing lucid dreaming with my partner, we both learned that she has aphantasia. I think it blew my mind more than it did hers. Things like, "I pictured that character so much different when I read the book" after watching a movie-- she always thought people were just saying that because they had different ideas of the characters mannerisms, or the text conveyed something different to them... Not that they could actually play out a scene in their head.

It got me thinking about a lot of ways we go about teaching. Math for example - my partner struggled with calculus in uni when presented an equation she hadn't seen something similar to before. It never occurred to me that people couldn't attempt to "graph" something in their head.
