The dream interpretation of diving into deep waters indicates the wealth of this world and prosperity.
If one dreams of diving into deep waters, being completely submerged, but not touching the bottom, then it means that one will achieve prosperity in this area. Because this world is a deep ocean. A sudden fall into water means money and joy.
We are talking about a dream where you are completely submerged, but you are in good health. If you start drowning then it becomes a bad sign and you need to understand the precise meaning of drowning. The latter is generally very negative since it indicates enormous financial losses or divine punishment.
