When dreaming of waves, notice the type of wave. Calm, clear waves indicate inner peace of mind. You are in touch with your emotions and are stable. Calm waves may also foreshadow upcoming decisions in your waking life.
Crashing waves, especially when heard, indicates your sexual nature and your need to be loving and tender with your significant other. Violent, unclear waves imply you have made a poor choice regarding an important matter.
Finally, if you are caught in an undertow or tidal wave, you have been holding yourself back. Something in your waking life has brought unshed tears to your eyes, what is it?
