Why I'm Afraid of Tidal Waves

Cymophobia is an abnormal fear of waves, sea swells and other wave-like motions. [...] Tsunamis, big waves, traumatic childhood experiences in the beach, waves hitting cliffs or rocky regions, tidal waves, floods, wave pools and river waves can easily trigger cymophobia. The fear of waves can be treated. It may require hypnosis, psychotherapy or even acupuncture. Cymophobia forces patients to live far away from the oceans, rivers and lakes. The symptoms of cymophobia are vertigo, dizziness, headaches, feelings of nausea.

I can recognize my worst phobias by how they affect my subconscious mind.  If I dream about something in a negative way, I know it must truly be a real fear.
