This post helped some people last time aphantasia came up so I’m just copy pasting the whole thing.
I had absolutely debilitating insomnia for my entire life. In the last couple of years I discovered something interesting. I’ve got a condition called aphantasia which means that I cannot see any images in my mind. For my whole life I heard the phrase counting sheep and thought it was a metaphor. Just like. Thinking about sheep since visualizing wasn’t something that I thought people could do.
Anyway, in researching about the condition I found an article online for an exercise where you can work on trying to visualize something. Basically you close your eyes and use the flashing remnants of vision to try to force a shape to exist. Sometimes you need to push on your closed eyes and a little pressure will cause some patterns to appear. You’re supposed to do this exercise while talking to someone outloud. Even if it’s just making a recording. The article I read said you must say it out loud or you will fall asleep. Me having never fallen asleep in my life without hours of concerted effort completely ignored this warning and much to my surprise it absolutely made me fall asleep within minutes.
Ever since then I’ve been able to use this technique to fall asleep every night. It’s like my mind finally learned how to do it. Most of the time I don’t even need to do these exercises any more.
That being said I was so pleased with this side effect I never even tried the say it out loud to try to improve mental images and I still can’t see anything in my minds eye. But being able to sleep every night without fail is a freaking miracle. So I highly recommend giving it a shot.
Oooohhh, that's what they meant. Yes, I can create movies in my head for fun, and do it so much and so well that watching real movies can be disappointing. I do find it hard to just model like blender though without imagining more context that just the apple. It's easier for me to imagine rotating an apple in my hand than imagine it rotating without any reason behind it. My brain send to care about the where and gets bored if only made to focus on the what. Probably has something to do with my ADHD
Aphantasia is the inability to "see" or "hear" in your head. While it's surprising to learn that people think differently (both for people with or without aphantasia), it has almost no consequence for daily life, except maybe for making it more difficult to remember past events.
When I was like 5-8 probably I used to not know how maglevs worked and assumed that the magnets just pushed them forward without any electricity. The maglev perpetual motion generator worked very well in my head though.
Where it gets hard is when you're looking at a 6-membered ring with stereochemical centres and trying to visualize it in a 3D chair or boat. Then rotating that 3D shape around in your head keeping the correct stereochemistry.
Then I tried putting a face on it. That didn’t work.
On a whim I searched for an image of an apple with a face on it, found one, and found it easy to rotate that imaginary apple and face.
I can imagine drawing a face on an apple, but find it harder to keep it in my brain if I rotate it.
I wonder if the brain has an easier time taking a “snapshot” of something you’ve taken in from eyesight and manipulating it rather than generating an internal image from scratch and holding that image while working with it.
