One of my favorite shows growing up was Ghost Whisperer.
Personally, I never at that time of life truly believer in life. But its bit silly for me to dismiss it entirely, because in every story Ghost have been known to store valuable information on their lived experiences and there experiences in the afterlife.
In the show Ghost Whisperer, there were Ghosts that leaned more Holy and ghosts that leaned more Unholy.
And on my personal account, I discovered that Ghost truly are real. Which proves some things they put on Television has truth to it. Fortuantely, we have those in heaven to protect us and keep us safe from forces of darkness.
