Its possible you are having Myoclonus
.Visit a Neurologist
and get an opinion and an EEG done(especially with sleep deprivation
), if he or she deems it necessary after taking a closer look. The doctor should also be able to help decide if this is occurring as part of late onset Juvenile Myoclonic Epilepsy
. Also share with your doctor if you have had instances of dropping objects during day time.
Kindly get back if you need further assistance. Hope this helps.
