It is said that if you eat a salted herring on Halloween night just before you sleep, you will be visited by your future husband or wife. He or she will come to offer you water and quench your thirst, in your dream.

To see an image of your future spouse: Eat a whole salted herring in three mouthfuls, retire to bed without a drink and don’t say a word. That night you will dream of your future partner.
To know if a future husband will be attractive and trustworthy, throw the white membrane of a herring at a wall. If the skin sticks to the wall and is not a crooked shape, your future husband will be attractive and trustworthy. If the herring skin sticks crookedly or fails to stick, your future spouse will be undesirable.
