Protection from Ghosts

One question I was recently asked was about protecting yourself from ghosts or spirits when you're sensitive to them. Here's something I learned from reading books by others: Imagine yourself surrounded by God's white light of protection- kind of like a shield.
This white light can be pictured around you whenever you go into a house that you may think is haunted or anywhere at any time. Usually when I get ready for sleep, I envision a white light around me and my family.
On the nights that I forget to do it, I tend to wake up at 2:30 a.m. or 3 a.m., when the spirits seem to be most active. The white light of protection really seems to work, and I believe that James Van Praagh and Maryann Winkowski mentioned it in their books. Give it a try!
