I'm nearly 40 and about 5 years ago learned about aphantasia. I've never been able to visualise, if someone said picture a red ball all I can see is grey. Nothing, no matter how hard I try.
A few weeks ago I'd seen a post on Facebook about an inner monologue - again I can't "hear" a voice or anything - it's just empty with thoughts of what I need to do. I didn't realise that an inner monologue was an actual real thing.
Do you all have one and what is it like?
