For an accurate interpretation of a swimming dream, all the details of water, weather, and other conditions should be considered, but as a general guide: If you dreamed of swimming in the nude, it predicts good luck in all that concerns you. To dream of swimming in a suit suggests an upcoming social embarrassment or disappointment. To teach someone to swim forecasts an increase in material wealth. To dream of swimming toward the shore prophesies security but only through diligent effort. To swim in a pool is a warning of hidden hostility around you.
