This Is What Happens When You Scream Out Your Window In Sweden At 10PM

Every night at 10pm Swedish students open their windows and scream for several minutes but nobody knows for sure how the phenomenon started.

Have you ever felt so stressed out or anxious that you just want to open your window and scream at the top of your lungs?

Well, students in Flogsta, a residential area in the Swedish university town of Uppsala, do just that when the exam pressure gets too overwhelming.

No one knows exactly how the Flogsta roar, or Flogstavrålet in Swedish, started, but every night at around 10pm students take to their balconies, roofs and windows to scream out their anxiety.

And the phenomenon has spread to other university towns and campuses, too, such as Lund, Linköping and Stockholm.
