As superstitions go, this is one which is followed almost in every country of the world. This superstition states that if anyone of your ears is burning or itching then someone is talking about you behind your back. Again, as with almost all superstitions, the origin of this one is also disputed by many, but still, the majority agrees about one origin.
In the old Roman Empire, there was a saying that if your ears are itching then someone is talking about you in your absence. That is thought to be the root of this superstition. Even in the old Roman scriptures, written by Pliny, there are references to this superstition. Sometimes we get weird gifts from our ancestors, this superstition being one of them.
There are two parts of this superstition, and both Pliny and Plautus have stated in their writings that scratching of the two different ears signifies two different things altogether. It has been the belief of a man for centuries that the right side is signified by goodness and everything that is positive in the world, while the left side stands for darkness and everything that is evil. There are few places where the ears and thumbs are linked in this superstition, while most believe in the simple one.
Even in English Literature, there have been plenty of references to this superstition throughout the ages. Poets like Geoffrey Chaucer, writers like Charles Dickens, who shaped the face of English Literature have placed this superstition in a number of their texts, and that is why this is one of the most famous superstitions in the world and almost every country believes in an iteration of this.
