Netflix is urging people to stop blindfolding themselves in a challenge inspired by horror film Bird Box.
In it, a mother - played by Sandra Bullock - has to wear a blindfold so she doesn't see mysterious forces which cause people to take their own lives.
Some people have taken things a bit far replicating it, though, and have almost injured themselves by walking into walls and oncoming traffic while wearing blindfolds.
Netflix says they "don't know how this started" but have one wish for 2019 - that people don't end up in hospital because of memes.
