People who have been in a coma are sharing their experiences online and let me tell you, some of them get pretty bloody weird.
Posting in the r/askreddit one Reddit user asked: "Those who have been in a coma, what was it like?" and it wasn't long before replies started rolling in with lots of people saying they'd had hallucinatory dreams and others saying they didn't remember a thing.
Some of them were quite touching, with one person posting: "I was in a medically-induced coma for three days during my cancer treatment.
"My identical twin brother died around a year prior (also to cancer).
"The entire time I was in the coma, I was with him. We were in a large green field with a lot of sun, and my conversations with him felt real."
Someone else said their wife had been in a month-long coma and after bringing their children they had a conversation about the best holiday they'd ever been on, with the kids all in agreement that it was a trip they took from Las Vegas to Arizona.
They added: "My wife heard it all but in a hallucinatory way.
"We talked about driving all over and seeing all the incredible sights. We talked about rides and amusements along the way. It was nice, then they kissed her goodbye saying, 'See you soon'.
"My wife now has - nearly 10 years later - a vivid memory of a second Arizona vacation she went on with us. She even asked me early on after she woke up if we had gone on vacation recently.
"Her mind went through every detail we talked about and even added to it as if it all actually happened. The memories of it are as real as any."
Another described it as similar to 'when you're little and wake up at a friend's house and don't know where you are', while someone else said they were in a coma for four day and it 'felt like a power nap'.
Which is a whole lot nicer, not to mention less creepy, than the person who said their young daughter was placed into a coma following a near-drowning.
They added: "She made a full recovery, but the things she told us freaked me out. She told us she played mermaid tea party with my dead parents, then described how she was denied entering the gates of heaven because 'St. Patrick' told her it wasn't time yet.
"I know it's supposed to be St. Peter, but I wore a shirt that reads: 'St. Patrick is my homeboy,' and she exclaimed excitedly that she had met him."
Well, that get's a big nope from me.
