During this time, body movements seem to speed up anywhere from 1.5 to 3 times their normal pace, creating that trademark “fast feeling.” Sounds may also be amplified, often to a physically painful degree.
People with tachysensia experience episodes where everything appears to be speeding up, and sounds become unusually loud. These episodes are short in duration, usually lasting no more than 10 minutes, and unpredictable in nature, making them difficult to study. They are known by many names, including quick-motion phenomenon, the rushes, rapid spells, and fast feeling.
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.
How do you experience this exploding head syndrome? I have some weird sensations every now and then since about 3 or 4 years that might fit into this description, I call them ‘brain zaps’ since I have not found anything related to it before. For me its a brief pop-like sound always connetcted with visual lightning sensation as well as electric tingling, it freaks me out every time I have it, scary in a way. Usually I have it a few times in a row when I try to fall asleep. I figured out it appears when I have alot of stress, am in overthinking mode and feel restless or have insomnia. Then again, its gone for weeks/months. Would be great to finally have a name for this, Iv’e searched for this quite a while already.
The other sensations sound familiar as well, thanks for sharing, will read through this as well.
What I think may be exploding head experiences are like this: It always happens towards the end of a daytime nap or after most of my nights sleep. There are very bright white light(s) and then a very loud crashing sound. The sound could be described as either an explosion or something big and heavy falling onto a concrete floor. Its deep and there are no high pitch notes to it. The first time it happened, I dreamed that there was a very big explosion like a nuclear bomb that went off over the sea (I lived on the coast at the time) and I thought it was real. I woke up and ran to the window to check, but there was nothing. Since then I've had it a handful of times and it usually wakes me up. My hearing feels a bit impaired afterwards, like I have heard an actual loud noise.
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.
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.
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.
