Psychic Self Defense

What is psychic protection and why do you need it? Maybe you find yourself having issues like insomnia, nightmares, poor sleep, or low energy levels. Does this occur around certain people and/or in certain places? Do you easily lose a lot of energy in these conditions? Are you regularly lacking in energy? Then you may need psychic self-defense to protect yourself against everything that is not serving you on your way to enlightenment.
