Have you ever found yourself drifting off to sleep and suddenly felt as though you were falling through your mattress, forcing you to wake up with a sudden jolt?
It's a horrible sensation, but it turns out that over two-thirds (68%) of us have experienced the random twitch, which is known as a "hypnic jerk", or may sometimes be referred to as "sleep starts" or "hypnagogic jerks".
New research conducted by sleep tech firm Simba has uncovered that around 29% of us report experiencing hypnic jerks regularly, and although anyone can be susceptible, their research found that women experience the jerks more often than men, while 82% of 16-25 year olds asked said they'd felt the sensation before.
