If you dream that you hear a pouring rain, very soon things that will mightily please you will happen.
If it is a drizzle, you feel disappointed because of small earnings.
If you dream that you are wet, you will encounter obstacles in the road ahead.
But if you see your loved one walking towards you, wet under the rain, then you rest assure that h/she will prove worthy of your trust.
Sometimes this dream is triggered by external sources such as a cars headlights or the light from a match.
