Numerous studies have shown that a lot of people experience an odd feeling of drifting off while falling asleep at least once in their lifetime. The sensation feels as if you’re falling down or as if something is hitting you. In the past, science couldn’t explain the reasons behind this phenomenon; however, newest studies have come to a conclusion.
Known as the hypnic jerk, when the ‘falling down’ occurs, the person immediately wakes up. Some people have reported feeling as if they were being choked or getting hit. If you frequently experience this phenomenon, you should reduce the amount of caffeine and tobacco, since there is scientific evidence that these ingredients increase the chances for the sensation.
At times, this could be a sign of lack of sleep or medications like Adderall and Ritalin. The sensation is a result of the body’s exhaustion and the brain thinking that you’re not falling asleep but falling down, which results in waking up.
