Before you go to bed, fill a glass with water and place it at the head of your bed so it will be beside you when you sleep.
DO NOT drink the water - it is to catch any unwanted energy around you.In the morning, using your opposite hand, empty the glass into the toilet and rinse it three times (emptying each into the toilet as well). This will "flush" away what was in the glass.
The symbolism of using the opposite hand is to stress that you REFUSE to take back what the water has collected during the night. If you are still having problems, you may want to add a small piece of camphor to the water. This will help to dissipate any negative thought forms.
