Your leaking at your clearance lights. You will have to take out your storage compartments above your windshield and use silicone caulk around the inside screws for the lights and then you will have to also caulk around the lights and the screw holes on the outside around the clearance lights.

Clearance lights are common on Semi-trailers and taller vehicles. What they are are lights at the top of a vehicle that marks the outline so you can make sure you can clear an obstacle. For example: Look at a big truck going down the freeway at night, see those lights at the top of his trailer? those are clearance lights. These mark out the outline of a vehicle so you can see them and so the driver can make sure if he is going under something he will clear it.
The lights in your dream probably symbolize information: en"light"enment. Turning off lights suggest limiting your sources of information.
