Feeling a sense of stepping into emptiness while sleeping can lead to physical tremors. This behavior may be uncontrollable by one's own consciousness, and it is a normal physiological response. However, it can also be a manifestation of symptomatic myoclonus, a lack of calcium in the body, or excessive physical fatigue.

Causes and Considerations:

1. Feeling a sense of stepping into emptiness while sleeping may be a manifestation of symptomatic myoclonus. If accompanied by symptoms such as headache or dizziness, it is recommended to undergo a brain CT or MRI scan to determine if the myoclonus is a symptom of a brain lesion.

2. This phenomenon may also be a reflection of calcium deficiency in the body. Low blood calcium levels can lead to increased excitability of nerves and muscles, resulting in spasms and tremors. Therefore, in such cases, it is advisable to increase calcium intake by consuming calcium-rich foods such as beans, milk, and bone broth.

3. Another possible cause of this situation is excessive physical fatigue or mental stress due to various factors, which prevent relaxation. During sleep, the body naturally enters a relaxed state, and the alternation between tension and relaxation can lead to tremors. If this occurs, it is recommended to reflect on whether there have been any recent feelings of tension. It is important to release physical and mental stress, maintain a relaxed and pleasant state, and pay attention to adequate rest and potential health risks.

Young people experiencing this phenomenon should be mindful of their daily diet and ensure a balanced intake of nutrients. For older adults, it is crucial to take this seriously and undergo a thorough physical examination.
