It's something none of us like to think about, but eventually there comes a day for us all when we shuffle off our mortal coil - and the things people say on their deathbeds might shock you due to their creepiness.
When it comes to end-of-life, there's a whole world out there that, let's face it, we know nothing about.
The internet has connected us with people who think they have an inkling of what it could be like on the other side.
A hospice nurse, Julie McFadden, has set out to demystify passing on and urges people not to be scared.

She has also opened up about the things patients 'see' just before dying.
She said: "One of the main things that happens to almost everybody, it's usually about a month before they die, they start seeing people who've already died.
"It's always people who bring them comfort...so I say family members - but it's only really family members if you had a good relationship with them."
She continued: "They will say, 'Hey I'm coming to get you soon, you don't have to worry about anything we'll be here around you'.
"Most people who experience this are completely lucid - they're alert and oriented, they're not actively dying and hallucinating."
And now some doctors and nurses have opened up about some of the creepy things patients have said just before dying.
In a Reddit forum, a user asked: "Doctors & Nurses of Reddit, what was the creepiest last words you heard from a patient right before they died?"
And the responses came pouring in.
Horrifyingly, one person said: "Surgeon here. A man on his deathbed kept repeating 'the body is in the woods next to the oak tree' over and over until he passed.
"The police were notified and searched some woods behind the man's house but never found anything."
Admissions of potential guilt must be quite commonplace, as another person said: "I overheard an old lady whisper this to her old husband dying of kidney problems.
"'You are going to beat this, you got away with murder, this is nothing'."
A third person added: "My grandfather on his deathbed said 'they have no eyes,' still give me chills."
Another said: "My mom was watching over my great-grandfather in the hospital. He'd been unresponsive for a day or so, when suddenly he said: 'It's about damn time you got here! I've been waiting!' And then he died."
We're not sure we'd be able to sleep after hearing all of that.
