Optical illusions have a way of playing with your head that can make certain images completely incomprehensible to our human brains.
Whether they are playing with your senses or how you perceive depth there is often a logical way to explain what you are seeing although it often seems impossible.
This brings us nicely to this picture shared on Reddit by user OrangeLimey and features a sign which reads simply as 'coffee.'
However, the shadow on the wall directly behind it features only one 'f' making it read incorrectly as 'cofee.'
What on Earth is going on? Needless to say, this image broke the subreddit it was shared in as people couldn't quite get to the bottom of it.
Some people thought that they had figured out and we think we understand now but we honestly aren't sure.
