If you have an intense fear of spiders, now would be the time to move away.
Residents in a Brazilian state have witnessed what some may find an incredible sight – while others find themselves paralyzed with terror.
Video images show large groups of spiders over Minas Gerais – a large state of the interior of southeastern Brazil.
Local residents said they saw the skies "raining spiders", while experts say it is simply something typical of the region when it is hot and humid – spiders form a huge temporary collective web.
In a video posted online, the shock of local man João Pedro Martinelli Fonseca is evident.
"Holy crap!" He says.
People all over the world shared the images and expressed their own shock at the phenomenon.
Some were quick to share how scared they are of the crawlers.
While others compared it to a scene from the 1990 comedy horror horror film Arachnophobia – whose title is taken from the word meaning the extreme and irrational fear of spiders.
The film, directed by Frank Marshall, is based on an alien spider who finds a way to a small town in America and then creates a kind of deadly arachnids.
The plot takes a gloomy turn as city dwellers begin to die after being bitten by spiders.
