Ive had the same experience with everything feeling like it was in fast forward, but with mine it all felt slow, i could feel and see them simultaneously happening, its happened all my life, and i dont really have an affective way to stop it either, most years it only happened a handful of times, some years it would happen couple times a month, with the feeling of fast and slow, i could feel the distance between everything warping and a needle like pressure throughout my body but alongside that was a bloatedness pressure too, i could spead it up and make everything go really fast too, and peircing sound in the air that would fluctuate in volume
