Sleep Protection

Mix salt and water from your altar in a small vessel. Starting at the North side of your bed, going clockwise, sprinkle the salted water while
saying:

Water and Earth
Where you are
Cast no spell
Or adverse purpose
Haste if not
In complete accord with me
As my word
So be it.

Visualize a protective box around your bed. And if your head board is against the wall, pull the bed out before you do this, or walk over the bed.
