I readed many articles about crystals and their aid in various situations. For example Amethyst is said that can aid insomnias, Calcite, Hematite and Iolite in astral projections, Moonstone intuition, clairvoyance etc. Anyone has any experiences in working with gems?
I suffer from insomnias for the last 5-6 years. I was once cured by visiting a person who is expertise in bio-energy work and he helped me a lot, but when i stopped visiting him and getting my weekly threathment, insomnias returned. One month ago i bought Amethyst gemstone and by the advice of the sales man i keep it under my pillow. Insomnias are almost gone and i have very clear vision of my dreams (which some times are lucid).

Anyone has any comments or experiences about other crystals?
