The first thing I would do is ask your parents to take you to see your pediatrician
. Your pediatrician is the doctor who knows you best, and they can evaluate you for the presence of any serious medical conditions.
The most likely cause of your symptoms is something called sleep paralysis, which is a relatively common condition in which a person wakes up before the brain's sleep mechanism becoming fully disengaged. This can lead to a very unpleasant sensation where someone is awake but cannot move the body. There may also be other symptoms, such as the ones that you describe.
Mild intermittent cases of sleep paralysis do not need treatment. However, if this becomes a recurrent issue, it definitely should be evaluated. Often, worsening sleep paralysis is associated with certain lifestyle factors, like sleep deprivation. It may also be associated with various medical conditions, including seizures and narcolepsy.
Your pediatrician will be able to perform a complete physical examination. Based on what they find, they will be able to help decide whether any treatment is needed or whether any additional workup or visit with a specialist doctor, such as a neurologist
or sleep doctor
, is needed.
