we are traveling italy by sea. we are somewhere and ancona is far away but no ships go there and you can only go by swimming. i am with another girl around my age and we are swimming. we start swimming toward acona in the middle of the night and i do not want to go. i would rather go during the day but we cant turn around. i think there is a shark. there is some kind of animal with a large fin rising out of the water. we also see dolphins.
