Thank you Heikki,
I wish I was there! What fun, but the mythology for young girls

I guess all that frolicking nakie would certainly cause a bunch of trouble in a big town.
There are various magical tasks and tricks for young girls (and boys) to perform on Midsummer Eve in order to know whether they would soon be married or to get a glimpse of their future spouse:
* Flower bouquet A girl picks seven or nine different species of wild flowers and places them under her pillow for the night. While sleeping, the face or the name of her future husband will be revealed for her in a dream.
* If a girl picks the nine flowers in nine different meadows, she will meet her future husband on Midsummer Eve.
* A girl eats salty food, usually salted fish, before going to bed. In her sleep she gets thirsty, and he who brings her water in her dream will be her future husband.
* If a girl rolls around naked on a dewy field, she will surely meet her fiancé during the passing year.Meadow
* If a girl goes to stand at crossroads on midsummer night, she will meet her future husband.
* A girl goes up to a well to listen on midsummer night. If she hears a clinking of keys, it means she will become a mistress of a house. If she hears a crying of a baby, it means she will have a child.
* If a girl goes up to a well or a spring naked on midsummer night, she will see the face of her future husband briefly reflected in the water.
* A girl makes a wreath of fresh flowers and drops it in a flowing stream. If the current carries the wreath away, it means wedding for the girl, but if the wreath is caught somewhere along the way, it means death for her.
