I have aphantasia, meaning that I can't form mental images at will. Nor, in my case, sounds, smells, flavors, tactile sensations, or emotions.

When I close my eyes, I enter a blank world.

In this thread I'll try to express what that is like for those who don't have aphantasia. Image I've had the opportunity of participating in a research project on aphantasia at a major university. By "participating", I mean "letting them take detailed MRI snapshots of my brain as I look at pictures, try to imagine killer whales, and other things that brains do".
