As we grow, we develop such complex fears (darn that normal human characteristic) and could become such a road block to our own potential. A lot of fearful situations seem to be appearing strongly in your dreams.

You should not however develop the fear of lucid dreaming. I hope you find the courage to overcome these dreams and continue to explore lucid dreaming to expand your dreaming experience.
Sounds like you might be a natural, as you are already having vivid dreams.
Try to think or visualize positive outcomes, and get away from worrying or dwelling on the negative outcomes.
Good luck.
