Water climbing the stairs while you watch. Tradition reads the flood as pressure rising faster than it can be handled, from a source outside your control.
Floods tend to arrive in dreams during weeks when too much is happening at once, which is more or less how the tradition reads them: pressure rising faster than it can be handled, from a source outside your control. The water is nearly always described as coming rather than as already there.
Two halves of this image are read quite differently. Water climbing the stairs, seeping under a door or filling a room is associated with mounting demand and the effort of staying ahead of it. The scene once the water has gone, with mud, damage and a strange quiet, is read instead as what remains when a crisis passes, and dreamers commonly report it as sad rather than frightening. Both halves belong to the same dream, and people often move between them without noticing.
Interpreters going back a long way pay attention to what the water looked like. Clear floodwater is treated as feeling that is at least legible to you, however much of it there is. Thick, dark or debris-filled water is treated as confusion mixed into the pressure. Whether you watched from high ground or stood in it shifts the reading again.
For a great many readers this is not a symbol at all. Anyone flooded out of a home, or living somewhere it happens most winters, may be dreaming about a real event and a real fear, and symbol dictionaries have nothing useful to say to that. Even setting such experience aside, heavy rain outside the window has a way of finding its way into the night. What water means to you personally comes first, and the traditional reading is only worth adding afterwards.
