The sea means fantasy, adventure, one’s dream, life as a whole, desire for adventure, etc. The dream of dark blue waves in the dark sea suggests that homes or businesses will be destroyed or in extreme discord. It’s a tough situation. It is also an indication that we should bear and try calmly. If you act rashly as you like, you will be in a worse situation. It may not be a real situation, but a dream that expresses the extreme intensity of internal conflict. Efforts should be made to objectify and observe what is making you so hard and heal yourself.
