My biggest 3 fears are old age, as I age that decreases, sharks, i wanna free swim with mako sharks off north island of NZ, prob last thing I do, but i'd be honoured. I also love ALL predatory animals, so a good portion of that fear becomes intrigue. Also a fear of heights, open heights, where I can fall, no fear of flying, etc. A common belief in some witchcrafts is that one attracts their fears. If you think on it and pay attention to it, you might see a valid point. Accept your fears & they won't haunt you as much (phobias are a little harder for this).
I used to have lots of BAD dreams involving water or/and snakes .... got quite irritating. Once informed water in dreams was a fear of your emotions, they stopped for a long while, and rarely occur, in some cultures snakes in dreams is sexual frustration .... well that's a little out of my hands ... lol.
