Sleep Paralysis: Debunking the Myth of 'Ketindihan'

Have you ever experienced waking up feeling paralyzed, unable to move, with an overwhelming sense of dread? This phenomenon, commonly referred to as 'ketindihan' in Indonesia, is often shrouded in superstition, with many attributing it to supernatural forces. However, science provides a logical explanation for this unsettling experience, revealing it as a purely medical phenomenon known as sleep paralysis.

Understanding Sleep Paralysis: A Scientific Perspective

According to Dr. Daniel Thomas Suryadisastra, SpN, RPSGT, a renowned sleep specialist, sleep paralysis occurs during the transition from the Rapid Eye Movement (REM) stage of sleep to wakefulness. The REM stage is characterized by a state of profound muscle relaxation, allowing for vivid dreams. When we awaken during this phase, the body is not yet prepared to move, leading to the sensation of being paralyzed.

“What we call 'ketindihan' is actually waking up while the body is still asleep. This is called sleep paralysis. We wake up during the REM phase when our muscles are completely relaxed. We're awake, but our bodies aren't ready to move yet,” explains Dr. Daniel.

Hallucinations: The Brain's Transition

The fear associated with sleep paralysis is often amplified by vivid hallucinations, further fueling the belief in supernatural interference. These hallucinations are a consequence of the brain's ongoing processing of dreams during the initial moments of waking. The abrupt transition from the dream state to consciousness can create hallucinations that feel incredibly real, contributing to the sense of being trapped or under attack.

“Sleep paralysis often comes with hallucinations. This is because our brains are still in the REM phase, when we're dreaming. We wake up, but our brain is still connected to the dream. Once the REM phase is over, we'll be able to move again. So, there's no need to worry,” adds Dr. Daniel.

The Scientific Reality

In conclusion, sleep paralysis is a scientific phenomenon that arises from the abrupt transition from the REM stage of sleep to wakefulness. It is not a manifestation of supernatural forces and can be explained through the understanding of the sleep cycle and brain activity. As Dr. Daniel emphasizes, the fear associated with sleep paralysis is a temporary state that subsides as the REM phase concludes, allowing the body to regain its ability to move.
