Coma can be described as a "state of prolonged unconsciousness" in which a person cannot be awakened, does not respond to stimuli, and cannot initiate voluntary movements. There are a number of reasons that a person can slip into a coma, and sometimes coma is induced for medical reasons. Whether medically-induced or not, there are a number of celebrities who have been in a coma and woken up to tell the tale.

Legendary actor Burt Reynolds struggled with drug addiction at certain points during his life, and he once fell into a coma after he stopped taking his sleep medication cold turkey.
He spent eight or nine hours comatose in a Los Angeles hospital, where he was apparently able to hear doctors saying, "we're losing him" and telling his wife to say goodbye.
In 2001, actress Sharon Stone suffered a brain aneurysm. She was lucky to survive the incident, which was so serious that she spent two years learning to walk and talk again.

Rapper Lil' Wayne suffers from epilepsy, which has hospitalized him a number of times. In 2013, there were reports that he was in a medically-induced coma after a number of seizures.
After the incident, however, the media was criticized for exaggerating the seriousness of the incident and doubt was cast over whether the musician had been in a coma at all.
Nirvana front man Kurt Cobain slipped into a coma in 1994 after he overdosed on champagne and Rohypnol. He only stayed unconscious for the day, but stayed in hospital for five.
The 'Smells Like Teen Spirit' singer survived that incident, but sadly it foreshadowed his tragic death, which was to occur later that year when Cobain took his own life.
In 1999, Martin Lawrence tried to lose weight for a role by jogging in the heat wearing multiple layers of clothing. When he got home, his temperature was 41.6°C (107°F).

In 1973, musician Stevie Wonder was involved in a road traffic accident while on tour in North Carolina. His car went into the back of a truck and he fell into a coma.
He remained comatose for four days, and when he woke up he discovered that he had partially lost his sense of smell and temporarily lost his sense of taste.
In 1967, the notorious stunt performer Evel Knievel attempted (and failed) to jump over the fountain at Caesar's Palace in Las Vegas on a motorcycle.
The stuntman suffered a number of broken bones and was rushed to hospital. There were reports of a 29-day coma following the accident, although these were refuted by his wife.
Grateful Dead front man Jerry Garcia suffered from diabetes and in 1986 he slipped into a diabetic coma that nearly killed him. He remained comatose for five days.
After he came out of the coma, Garcia spoke publicly about his experience of unconsciousness as being surreal. The coma forced him to relearn to play the guitar.
Former F1 champion Michael Schumacher suffered a skiing accident in 2013 and was put into a medically induced coma due to the injuries he sustained.
Sources suggest that Schumacher was in the coma, which was intended to reduce the swelling around his brain, for around six months, before doctors lifted him out gradually.
