If you see someone being immersed into the water, it is not a good sign and might represent misfortune whereas coming to the surface out of water signifies revival and renewal. You must change your personality to the better self, as this will lead you to fortunate and prosperous future. On the sublimated side, the dream refers to researches of God. This is the time when you started realising of who you are and what do you do in this world, especially what is your purpose in life.
