The sensation of falling when you are in bed is known as a hypnic jerk. It is believed to be caused by the brain's misinterpretation of muscle relaxation as a signal that your body is falling, hence the sudden jerk or jolt awake. Stress, anxiety, irregular sleep patterns, or excessive caffeine intake can contribute to experiencing hypnic jerks.

The mini spaz attack, often experienced when you're in bed half asleep, is known as a hypnic jerk or sleep start. This sudden muscle contraction can occur as you transition from wakefulness to sleep, often accompanied by the sensation of falling. It's a common phenomenon and typically harmless, though it can be startling and disrupt the process of falling asleep. Many people experience this at some point, and it's thought to be a natural response as the body relaxes.
