A flood stands for feelings that have overflowed their banks — too much at once, spilling into every room of life. Water rising inside your own house is usually read as emotions or worries reaching places that used to feel safe and private. Escaping to higher ground is read as the instinct to find perspective, and watching the water from a distance as observing a situation rather than drowning in it. Old flood myths also give the image the sense of a clearing away before a fresh start. It can help to notice where something in your days feels like it is overflowing.
Does the traditional reading fit your dream, or did it mean something else to you?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
