Dead people don’t just suddenly sit up like in the movies.
It’s of those great, creepy stories kids tell each other, but it’s not true, according to those who know.
It is true, though, that dead muscles can go through slight spasms.
Funeral workers sometimes massage the legs and arms to relieve spasms in the muscles while washing, cleaning, and dressing the body after death.
It is believed this myth began during a time when dying people were often pronounced dead before they actually died.
The person “came to” long enough to sit up or raise their head toward the end.
But as far as anyone knows, this can’t happen postmortem.
