It’s like knowing a cow is the room next door. You are aware of the cow but you can’t see it. If someone says the cow is brown, you are now aware the cow in the room next door is a brown cow but you can’t see it because it’s in another room. Except the other room is your mind.

I don’t need to see a cow to imagine it in the next room. Same concept.

It’s easy to figure out if you have aphantasia. Think of a cow. Do you see a cow?

It’s not a condition or a disability, it’s just a different way that some brains work. Don’t fall into the trap of - it’s outside the majority so it must be a deficiency. Most people with aphantasia don’t even know they have it.

Also, strangely I can rotate a cow in my mind, but there is no visual feedback. I “feel” the cow rotating. I choose where in the physical space to project the imagined cow and there is the imagined “physical” sensation of the cow spinning as if it’s an extension of my mind. I can imagine sound as well. But I don’t see anything.
