Yes to all of them but sometimes stuff gets muddled as I'm a little synesthesic too
Certain words and numbers have certain colours or sounds in my muddled mind a few have smells or tastes
If I read a book or a short story I can visualise it as a film or tv show, and vice versa
Musically I can summon up most music that I know on cue but then I've always been quite musical though. I freak myself out on that at times! I can hear a few bars of something I've not heard in DECADES and instantly recognise it - that's particularly true when it's a song as I'm very tuned into voices
Sometimes when I'm watching a tv show or film if an actor first "appears" with their voice only my ears prick up and I'm instantly "I know that voice!" Happened most recently with William gaminaras appearance on Death in paradise (I wasn't looking at the screen just heard the voice and that got my attention) and I've not seen anything he's been in for YEARS.
I've even had that happen in work situations when I've been in jobs where I had colleagues at other sites and not met them until several months into the role and then I meet them at a group situation and I can instantly pick them out by voice
With this in mind I tried watching a few episodes of "the masked singer" but I was put off by the silly guesses people were making when it seemed obvious to me quite early on who they were (the ones I'm familiar with anyway, there were a couple of surprises simply as I wasn't already familiar with those singers)
In terms of why
I have ocd which is supposedly due to at least partially malformations in the part of the brain that is also affected in asd's
I've not been tested but I've also had a few hcps suggest I may be on the spectrum myself. I'm almost 50 so I reckon it's rather pointless at my age but I have spent my life finding it very difficult to negotiate social situations, I'm known for my "directness" and while I can "do" sarcasm it was very much learnt rather than natural. I can disappear down learning rabbit holes quite easily (my internet search history and then million apps usually open at once on my phone prove this! It's usually only when the phone starts glitching I think to check and close things down but they're all linked to one main train of thought) and get tunnel vision and a few other things might also indicate that I may not be neurotypical.
Various quizzes I've tried assess me as more neurodiverse than neurotypical how much varies.
My brain is NEVER quiet I wish it was at least sometimes even in my dreams life is awkward and stressful and anxiety inducing
I have tried so many things over the years to quiet it - meditation, hypnosis, meds, mindfulness, various therapies...
Similar to pps I spent most of my life assuming everyone could do all this stuff then when I slowly realised they couldn't I found that very disconcerting.
It's very very annoying and exhausting!
