LEGEND OF THE WHISTLER

There is a legend that says that whistling inside the house is not recommended after 12:00 AM. This says that at this time the creatures from the other side hear the sound of the whistle and manage to get closer to the whistling person.
People who whistle while showering during early morning are said to be able to see shadows and spectres standing in the corners of the house.
If you want to try, during late night turn off the lights in the entire house and whistle for about 30 seconds. They say you will hear weird whispers and then you will feel cold air around you.
It's the creatures feeling your aura.
Would you dare to try it?
