Rarely, 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.
To conclude, 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 sleep specialist for more information. Take care and regards.
