This is very disturbing. I have a friend that suffers from similar dreams. Some techniques she uses to try to help avoid her traumatic dreams are aroma therapy with essential oils when she gets in bed and focusing on happy and grateful things before falling asleep instead of praying for all the problems in her family, life and the world. The aroma therapy is an essential oil mix with equal parts of frankincense, vetiver, and lime with a few drops applied to the back of her knees, neck and forehead. Hopefully, writing the post and understanding some of the symbolism will also help put an end to them.
