Vittra is a kind of creature that people in Sweden talk about in their stories and legends. Some people think that the Vittra are like tiny people who live in the forests and fields. They might wear hats and have long, white beards like garden gnomes that you might see in people's yards.
Some people say that the Vittra are like fairies, but they are not always nice like the fairies we know from stories like Tinkerbell. The Vittra are known to be a little bit mischievous and can sometimes play tricks on people. They might move things around in your house or garden just for fun.
For a long time, people in Sweden used to believe that the Vittra were real creatures that could bring both good and bad luck. People might leave small gifts for the Vittra out in the forest or fields just to make sure they stayed on their good side.
Today, people in Sweden still talk about the Vittra in their stories and legends, but most people do not believe they are real creatures anymore. But it's still fun to think about these tiny little creatures living in the forests and playing tricks on unsuspecting humans!
