Take a white household candle and light it without a word. Walk counterclockwise around your bedroom three times. As you do this, project simple protective phrases into the walls, floors, and windows such as "keep me safe" etc.... Next, walk clockwise three times in silence, meditating on positive, restful phrases. Finally, blow out the candle, whisper the word "sleep" and turn in for the night. Note that this spell does not need to be repeated to continue working. Instead, simply light the candle for a few minutes each night, then whisper, "sleep" again before getting into bed. When the candle is completely spent, repeat the original spell with a new white candle.
