Yes, I believe in the paranormal stuff and I am not ashamed of that.
NO ONE BELIEVES UNTIL...
And I don't blame anybody who didn't. I won't start a witch hunt! (pun intended)
I think that if you never have met anything paranormal, it's totally understandable if you don't believe in any of this.
So, it's normal that you won't believe in the paranormal until...
...something unexplainable would happen to you.
If you believe in God, then you have to accept the existence of demons. There is no light without darkness. Even the Bible mentions about demons and exorcisms.
PERSONAL EXPERIENCES
My family have a couple of ghost stories (just to name some highlights):
First, my paternal grandfather died when I was a kid and some time later many stuff starting to get lost in my home and reappearing again later. He didn't live with us, and while he was my paternal granddad, it was my mom instead the one who was certain that he was him behind of that. Some night, my dad was out working, I was slept and my mom was the only one awake (my brother hadn't born yet), so she "talks" to the air and she said to my grandpa that she knows that he love us very much but the thing about dissapearing stuff was scaring her too much, so she pleaded him to stop doing that. She didn't tell anyone that she did that for quite some time but right after she did the "talking", the stuff stopped to dissapear in my home.
Second, my mom was really close to my maternal great-grandmother and when my great-grandma was dying, the process took several time. One night, my dad got sudddenly awake and for a split-second he swore that he saw my great-grandma at the door of their room watching my mom. He awaked my mom and advised her to call to my maternal family's house since he thought that my great-grandmother had died. She phoned right away and they told her that indeed my great-grandma had died like half an hour ago and they were still making calls to tell all the family the sad news.
Yep, true stories. I gained nothing making up these.
101 ON THE WARRENS
The book is about the lives of Ed and Lorraine Warren, that they were paranormal investigators since the 1940's and they were quite known by clergymen of several religions, college scholars and even the military but it was until the "Amityville" case that they got publicity enough to be known by general public.
Lorraine Warren is still alive (2014 (when I read this book)) and she has clairvoyance skills. Ed Warren was a demonologist, one of the only seven demonologists recognized (at least on the 1970s) and the only non-priest person allowed by the Catholic Church to make exorcisms. Both dealt with hundreds of paranormal cases on the United States and England since the 1940s until early 1980s.
SOOO, THE BOOK...
The book was quite good and a very entertaining reading, however it didn't cover all the most important and famous cases of them.
While the book mentions here and there the topic of the "Amityville" case, it isn't exposed on detail. About that particular case, I don't know if it was a decision since the polemic status of may be a hoax. However, there are several other cases like the "Snedeker", "Union and Stepney Cemeteries" and "Smurl" cases, even the "Perrons" case, aren't commented in detail here, not matter when the publicity on the cover of the book mentions that that particular case that inspired the film of The Conjuring.
BUT...
While the cases that the book does cover are quite interesting and I didn't know about some of them.
Honestly expected a most complete biography of their cases, especially the most famous ones. I know that their career was quite long, but definitely the book should cover the most known cases.
However, the cases that the book covers, indeed are captivating, so I have no real complains and I enjoyed a lot the reading (and yes, it got real spooky at several moments!).
Besides the info and details about some of their cases, the book also it gives extended explanations about the differences between kinds of spirits, human and inhuman ones, and also the typical signals of the process of a haunting in any house.
Many of those cases with people involved in hauntings, they were guilty for being playing with books with dark rituals and most commonly with ouija boards. Certainly not matter if you believe or not in those things, there isn't any excuse to start playing with dangerous stuff like that.
In some really rare cases, the person affected didn't do anything to deserve it, they say that it's like one every ten years that this may happen.
So, in the most cases, someone in the family must do something to provoke the haunting.
Quite interesting enough, besides civilian families (in most cases), in the book is detailed a paranormal case on the West Point Academy and the military command there, asked for the Warrens to help them. And you can bet that so prestigious institution wouldn't call them if they wouldn't believe that they were dealing with something paranormal.
On the book too, they detailed various cases of hauntings and demonic possessions presenting the transcripts of recordings while talking with the possessed people.
And one of the highlights is that the book indeed cover the famous case of the "Annabelle" doll.
So, while I expected that the book would cover all the major cases of the Warrens, still the book is well written, quite entertained and highly recommended to any interested on the real deal of the paranormal phenomena.
