To hear a whistle in a dream means that you will be shocked by some sad news that will make you change your plans, refusing to entertain. Seeing in a dream that you whistle yourself, foreshadows some kind of merry case, where you will almost be the main figure. This dream for a young woman heralds unreasonable behavior, because of what she will miss the opportunity to achieve what she wants. If you dream of people who are loudly whistling - sleep foretells the grief of the disrespectful attitude shown to you by others. This dream can also be a sign of a future quarrel with a friend.
