My partner tells me my body vibrates violently sometimes when I sleep. I'm not aware of it, though. It's not every night, but often. Any insight?

Sleep study. Sorry if answered before. Occas shudder or twitch not unusual when passing through sleep cycles. A sleep study would be helpful to correlate with brain electrical activity, though it doesn't ring alarm bells for me. There are neurologists and sleep specialists here at HealthTap. .
