What is tachysensia?
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.
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.
