hypnic jerk Eric Thomas-Hill Asheville A hypnic jerk, hypnagogic jerk, sleep start, or night start, is an involuntary twitch which occurs during hypnagogia, just as a person is beginning to fall asleep, often causing them to awaken suddenly for a moment. Physically, hypnic jerks resemble the "jump" experienced by a person when startled, often accompanied by a falling sensation. A higher occurrence is reported in people with irregular sleep schedules. hypnic jerk’s tracks Deep and heavy by hypnic jerk published on 2013-05-13T22:27:35Z CRICKETS SLOW DOWN by hypnic jerk published on 2013-04-04T00:36:04Z My hairs favorite meal is the teeth of my comb. by hypnic jerk published on 2013-02-07T16:48:01Z Drone by hypnic jerk published on 2012-11-08T06:26:43Z Like It by hypnic jerk published on 2012-11-08T03:58:50Z Floot root by hypnic jerk published on 2012-10-10T08:24:25Z Play Your Flute (blockhead REMIX) by hypnic jerk published on 2012-09-18T01:26:45Z SSHHHHH (Cisum yalp ot deen ew REMIX) by hypnic jerk published on 2012-09-04T01:42:27Z Cisum yalp ot deen ew by hypnic jerk published on 2012-02-24T03:32:25Z Blee-uh-bop by hypnic jerk published on 2012-02-14T20:54:55Z
