Top Recommended Crystals: Amethyst, Pink Mangano Calcite, Smoky Quartz, or Prehnite Additional Crystal Recommendations: Ruby or Turquoise. Nightmares are associated with the Third Eye chakra. Place your preferred crystal(s) under your pillow or on your nightstand to help chase away and stop nightmares. This works well for kids too. In fact, both of my sons plus all of my nieces and nephews sleep with both an Amethyst and a Smoky Quartz. Amethyst
