When it rains, and you are in the water or looking into the ocean/sea, there's low visibility. I guess in a way, water is related to healing, to cleanse. As the rain pours, it also doesn't let you see far out, the reason may be because it wants you to focus on where you are at the moment instead of squinting your eyes trying to see what's ahead. When you heal, you must focus on you, entirely you, then you can start looking out.
