What does it mean to dream of a big frog chasing u in water and when someone grabs the frog by the mouth the frog starts to throw up tons of blood?

Chase dreams often represent real-life problems that the dreamer is avoiding, or running away from. This dream suggests that dealing with the problem will result in a bloody mess. Another possibility: in ancient folklore, the frog represents a girl's blossoming sexuality. A remnant of this folklore survives in the fairytale of the princess kissing the frog. Viewed in this light, the dream might represent an avoidance of sexuality, and fear of the bleeding (the consequences) that results from menstruation or loss of virginity.
