If you’ve visited Reddit this week, you may have already stumbled upon this intensely unnerving story about a haunted email thread.
It's been filed in the No Sleep category, which has been created for people to share their creepiest and most unsettling stories.
The No Sleep admin rules reminds us: "Remember: everything is true here… readers are to assume everything is true and treat it as such."
Which is why this thread caught our attention.
The begins with a simple email exchange between two friends; they haven't seen each other for a while and are catching up on their lives.
But things take a turn for Creepsville when 'Shaun' sends a frightened message to 'Ross', revealing that an old woman had startled him and his girlfriend Amy during a nighttime drive.
Things get steadily creepier after that.

Shaun becomes more threatening and erratic in his emails, insisting he wants to "dig up" the corpse of Ross' mother - which, understandably, leaves his friend upset.
But, when quizzed about what he'd said, Shaun had absolutely no recollection whatsoever - and insisted someone must have been playing a joke on him.
The final few messages reveal that Shaun has gone AWOL; his girlfriend has been unable to access him and he has not been in contact with Ross for weeks.
But then, out of the blue, one final email makes its way through.
Yikes!
