Now, I have been a HUGE fan of Ghost Adventures since season 1 (that is 10 years!!!). You laugh, you cry, you are terrified, and that is just watching the show.
When Zak Bagans came out with his first book, Dark World (co-written with Kelly Crigger), I immediately bought it, and to this day it is still one of my favorite books of his. It is about how he became who is today. Sympathetic to the spiritual realm.
He owns the Haunted Museum in Las Vegas (which I am planning to visit in December, so excited!!!), a museum that houses haunted items. I cannot imagine what it is like to even have just a few items in your house, let alone a whole building filled with them. To this day, I still believe one of my old dolls was possessed, it would play music and move when no one has touched it. I still have issues over that one lol.
You can follow him on Twitter, and interact with him (he is hilarious by the way), and get little clues on upcoming episodes of Ghost Adventures on Saturdays on the Travel Channel.
You can read his other books such as I am Haunted: Living Life Through the Dead (also co-written by Kelly Crigger), and again, watch Zak and his team on Ghost Adventures on the Travel Channel
