When you think of scary movies, images of monsters and unstoppable killers come to mind. But documentaries can also tell some horrific stories, too.
With Halloween around the corner, we delved into Netflix to highlight some of the most chilling non-fiction movies and TV series. We found everything from Errol Morris' classic that looked inside the mind of a killer, to a UK series that explores nurses who kill their patients.
Here are 14 documentaries that we dare you to binge late at night.
Note: Numerous Netflix titles drop off the streaming service monthly so the availability of titles below may change.
