I've actually been compiling notes to do this! I've been fascinated by how every time aphantasia comes up on HN or Reddit, there's always several people who either discover they have aphantasia because of the article or had recently discovered it, because they had always assumed that expressions like "mind's eye" were just another figure of speech or idiom. It's made me wonder if one could create a survey of mental/physical experiences which would double as a way of informing everyone about the various possibilities & what is the norm.
Aphantasia is just the tip of the iceberg - there's a whole laundry list of 'abnormal is normal' mental stuff out there.
A partial list: they vary from the various kinds of color blindness to anosmia (unable to smell!) to blind people regularly having vivid visual hallucinations (Charles Bonnet syndrome) to hearing voices (something like 10-20% of people occasionally hear voices) to lack of inner monologue to musical anhedonia (being unable to enjoy or be moved by music) to ASMR to misophonia to the nasal dilation cycle to 'intrusive thoughts' like 'the call of the void' to hypnagogia (hallucinations while falling asleep) to being aware of one's facial expression when talking to synesthesia to faceblindness to crying (I was shocked to learn that many women report shedding physical tears from sorrow on a weekly or monthly basis) to repetitive PTSD-like school dreams to long-running elaborate daydreams ('maladaptive daydreaming')...
(There's also the funny little lifestyle ones. Like, do you take shoes off or not? Do you take 'navy showers' or let the water run the entire time? Cereal then milk or vice-versa? Do you eat the same thing for lunch every day?)
