"At night, while you sleep, your conscious awareness is reduced, and so you are more exposed and vulnerable. This is why you must pay particular attention to your state of mind when you fall asleep. The dark entities need materials and energy for their work, and they find them in human beings, particularly when they are asleep. Why? It's very simple: during the daytime humans are swamped by their activities, so they make use of their own energies, but during the night when they are asleep their energies become available.

Of course, there are many people who will never accept that there are evil entities able to come and draw strength from them while they sleep. Well, if they don't accept it, that's their affair. But all those who wish to progress on the path of evolution must accept the existence of these entities and the need for shielding themselves from their wrongdoings. This is why, before going to sleep, they ask to be protected by the spirits of light."
