Being in a coma is one those experiences we all wonder about.
It is a state of unconsciousness, caused by a various medical conditions including severe head injuries, alcohol poisoning, low blood sugar in those with diabetes and brain infections.
It can also be medically induced to protect the brain during neurosurgery or as a last line of treatment for extreme trauma.
Someone wondered what it was really like and took their question to Reddit, asking users to relate their experiences – what did they remember? What was the recovery like? Did they have any weird dreams?
