Definitely sound sensitivity for me. Using AirPods Pro with no music on helps.

This is really interesting! I've had what I think are exploding head syndrome experiences, and I also have occasionally weird thought sensations where everything seems fast and it doesn't feel normal, almost like a pre seizure event. But I've never heard of Tachysensia so thanks, I've got some reading to do now.

Umm, I don't think so. I know my foot tapping speeds up and my heart rate goes up.

But I don't think I really perceive anything else as speeding up. And, if anything, sounds drown out.

My goodness. It’s a real thing?

I also have Alice in Wonderland Syndrome. Learning that AIWS was a real thing as an adult was shocking and then brought me a great deal of comfort, making me feel less insane.

Now learning about tachysensia i am equally shocked and comforted. It was always very scary when I experienced it as a child and would often happen specifically with my father, who was a difficult and often mentally abusive person. He was scary to begin with but sometimes his movements would become faster than a human should be able to move and he would be so much louder than anything else which made me so much more afraid.

I can’t believe this is a real thing. Absolutely amazing.

Oh, I finally found out what that thing is called.

Happens in bed, best thing to do is get up, stamp my feet and stare into a light. I definitely get the sound part as well, and a certain distortion of scale, like tiny movements seem huge and racing. Interesting to hear it's linked to ADHD, since I have ADHD.

Is there something like this but where I can feel like buzz in my head. It’s like all of my senses are vibrating. I can feel this vibration intensify when I move my eyes or turn my head. It’s usually coupled with deep task paralysis and disassociation from the world around me.

I wish I could find the right combination of words to describe this feeling. Back in the day we used to use these metal stakes pushed into the ground. Plug the stakes into a wall outlet and it drives the worms up out of the dirt, easy way to collect bait for fishing. Anyway, sometimes you had to twist the the stake in the dirt to adjust it a bit and when it was plugged in, those stakes have this weird electric buzz feeling. Closest thing I can get to describe the feeling.

Holy shit I’ve had this before and thought I was going crazy. Glad to to know it’s not just me

Maybe?

Things slow down but I don't and reality melts away except what I'm focusing on and speech gets amplified a shit ton.

I find it similar to runner's high (or workout high) kinda, except with runner's high reality is freaking gone.
