tidal wave, term properly applied to the crest of a tide as it moves around the earth. The wavelike upstream rush of water caused by the incoming tide in some locations is known as a tidal bore. In popular usage the term tidal wave also is often applied to any destructive wave or to high water not related to tidal phenomena. These latter waves are of two types: tsunamis, which are waves caused by earthquakes, and storm surges (see under storm).

Tidal waves or tsunamis suggest that you may be in a period of emotional upheaval. Anxiety, stress, and unconscious materials may be coming to the surface and affecting your daily moods. Giant tidal waves from your dream may be symbolic of current emotional unhappiness and psychological stress that may be threatening to destroy or uproot you. The outcome of this dream could reveal to you how much strength you have to “ride out” this storm. If you are not consumed, or you survived the tidal waves of your dream, be assured that you will survive the challenges of life and living.
