If you are looking for real stories that keep you on the edge of your seat, then this "A Haunting" Series, Seasons 1-4 is for you. A Haunting is a series that airs on Discovery Channel, and is based on stories from families, people, businesses, etc. who have encountered supernatural experiences. The stories are very well put together, and there are probably about 45 mins to each episode, (15 less minutes because there are no commercails). "A Haunting" takes stories and experiences from individuals and re-enacts them with actors. They do interview the people who did experience them, but change their names for privacy and protection reasons.
"A Haunting" is recommened by Discovery Channel for and 18+ audience, not because of language or sex, but because the stories are real and carry the potential to be disturbing. I would not recommend that you buy this if things like this really bother you, because some material can be bothersome; and I also would not recommend watching it before you go to bed, because it will be on your mind all night. However, I give it 5 stars because it is very well put together, and is very much authentic. It will keep you checking things twice after you watch it.
