Everywhere you go, there are so many signs sharing information, that you probably don't notice them all.
After all, they are usually informational at best, and innocuous at worst.
That is not the case when it comes to these sinister signs spotted by social media users in North America and the UK, and collated into a gallery by Bored Panda.
Among the creepy notices, is one on an office door, boasting that the space belongs to someone who is both a veterinarian and a taxidermist.
Another image shows an image that wouldn't be out of place in a horror film - a sinister clown at a fairground ride telling passers-by that they must be as 'high' as him to ride the attraction alone.
If this unsettling sign doesn't encourage you to stay away from this machine, then it's likely nothing will
Meanwhile, another warning notice lets people know that the machine it is attached to cannot distinguish between flesh and metal - and nor does it care.
And then another message, supposed to be supportive, shows just important layout is when sharing information. Instead of saying: 'We are all in this together,' because of the gaps between letters, it looks like it says: 'We are all in this to get her.'

At least this sign is clear and emphatic, leaving readers in no doubt at all that passing it would not end well for them
As if clowns weren't already creepy enough, this sign, featuring a slightly menacing looking clown enticing short people to go on a ride alone could give you nightmares
It's difficult to tell whether this sign is meant to be taken as friendly and caring advice, or as a threat
Simple error or a killer train that literally murders commuters when they reach a city in the north of England?
Whoever wrote this depressing sign appears to want everyone who reads it to be lonely and miserable
This sign on a train platform in the UK warns commuters that they 'must wear a face' to travel - it would be pretty creepy if they didn't! We assume it should say 'face mask'
