Tachysensia


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.

    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.

      It really does feel like a migraine prodrome or something doesn’t it. First time I’ve ever heard of another person experiencing this.

      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.
