hi,

too me this dream sounds like your life is feeling out of control perhaps you, the rain could be tears and sadness. Wisdom teeth are most of the time completely useless, some article i read recently says they are just leftovers from thousands of years of evolving which is why they are called wisdom teeth. so dreaming about your wisdom teeth could mean you are learning new things about yourself , the tiny fangs are suggesting that you need a more sharply and smartly about a situation make sure too think things through too learn the most from them.

hope that helpsl
