To induce dreams of a prophetic nature, fill a blue or yellow mojo bag with mimosa flowers and then place it beneath your pillow before you go to sleep. According to author Rosemary Ellen Guiley in The Encyclopedia of Witches and Witchcraft, blue is the color associated with psychic and spiritual awareness, and prophetic dreams. However, in his book on magickal herbs, Scott Cunningham lists yellow as the color corresponding to divination, psychic powers, and visions. I, personally, have always used blue or purple for this purpose, but you may use whichever color feels right for you. In addition, anointing your Third Eye chakra with an infusion of mimosa prior to sleeping helps to facilitate dreams containing prophecies.
