Hi, welcome tot he forum, vibration in muscles can occur due to abnormal nerve trigger, leading to twitching of a small group of muscle supplied by the nerve. It is a looks like a variant of Restless leg syndrome, but cannot be said definitively. The causes for this would be peripheral neuropathies, vitamin and minerals deficiencies, lumbosacral radiculopathy, spinal stenosis, excess caffeine intake, hypoglycemia, and hypothyroidism.
It can also be sleep related known as night starts can become unusually violent, very frequent, or repetitive, and confused for seizures. The phenomenon is restricted to sleep, and always or virtually always in the transition between sleep and wakefulness, and is not associated with other phenomena.
You need not worry; it will not harm your body and will wear off over a time. Maintain good sleep hygiene, be positive. I suggest you to consult a neurologist to rule out the cause and treatment accordingly. As such this would not be a matter of concern. Take care and regards.
