Possessed dolls, demons and haunted houses: Inside the life of paranormal investigator Lorraine Warren.

Lorraine Warren lived a life unlike any other.

One that took her travelling across the world encountering the bizarre and the unexplainable.

Years which inspired some of the world’s most iconic – and disturbing – horror films.

Lorraine – a celebrated paranormal investigator – lived a life dedicated to rescuing people from evil spirits.

She sadly died this week at the age of 92, 13 years after her husband passed away.

“It is with deep sadness that I must announce that Lorraine Warren has passed away,” Lorraine's son-in-law, Tony Spera, confirmed to The Patch.

“She died peacefully in her sleep at home last night," his statement read.

Her husband Ed was a demonologist, author and lecturer, with whom Lorraine, a psychic/clairvoyant and medium, worked closely to rid family homes of demons.

Demons that would go on to star in the nightmares of people all over the world who watched the films in which they featured - including The Amityville Horror, The Conjuring, The Nun and one of the most disturbing figures of the modern scream screen; Annabelle - the demonic stuffed doll that cannot be unseen.

The story of Lorraine and Ed's encounter with Annabelle is one that sends spines tingling.

It begins with an innocent children's toy - a Raggedy Ann doll purchased in an antique store. One that was once the possession a of nursing student, but now resides in a secure glass cabinet emblazoned with a sinister warning sign in Connecticut - part of The Warren's Occult Museum collection.

Before the doll was locked away, it had been the source of terror in the nursing student's home.

She and her roommate first noticed the doll changing positions or rooms without explanation, which eventually escalated to messages on paper and blood on the doll’s dress, and at one point violence.

Annabelle was particularly aggrieved with the fiancé of one roommate, who claims he woke up startled one night to the feeling of something crawling up his body. It was Annabelle, attempting to strangle him in his sleep.

He later claimed that upon entering a darkened room where the doll rested he felt something attack him. When he switched the light on, his stomach was covered in bloody scratches and the doll was on the floor.

The behavior terrified the roommates, so they called on the Warrens to intervene.

Lorraine explained that she believed the doll was possessed by the spirit of a deceased seven-year-old girl named Annabelle Higgins. Higgins had supposedly died on the land where the apartment stood. They performed a blessing in the residence before taking Annabelle off the young woman’s hands.

Their experience behind the 1979 original The Amityville Horror was similarly chilling, taking them to a haunted manor in the New York suburb of the same name.

It was this job, Lorraine once said, that stuck with her for years.

"Amityville was horrible, honey. It was absolutely horrible," she said at a press event for The Conjuring in 2013, reports Yahoo Entertainment.

“It was a very bad place,” Lorraine later recalled of the experience to Entertainment Weekly. “I remember when I was there and Ed said he was pushed to the floor as if a heavy blanket was pushed over him.”

In March 1976, with a news crew and a photographer by their side, infrared images of a demonic boy were captured inside the grand suburban home which still stands today.

It came two years after the horrific story of an entire family murdered by their 23-year-old son.

The son had claimed he heard "voices" telling him to travel from room to room, shoot dead both of his parents and his four siblings. He was given six life sentences. Today, he is still serving his time in a New York prison.

Before The Warrens' visit, another family had moved in to the home; The Lutz family. But they only lasted 28 days.

The young family claimed to have seen slime coming out of the walls, knives being thrown off kitchen counters, and a red-eyed creature resembling a pig. They recounted figures wandering inside the home when it was supposed to be empty.

George, the husband, said he once saw his wife levitating above their bed, and was woken up every morning at 3:15 a.m., the exact time that DeFeo killed his family.

The Lutz family eventually brought in a priest to bless the home, who was driven out in horror after a voice told him to “Get out!"

Lorraine - who was no stranger to evil spirits at the time - said her visit to the home following the priest's attempted blessing was even too much for her and her husband.

"It followed us right straight across the country. I don't even like to talk about it. I will never go in the Amityville house ever again. You don't know how long my career is; that's the only one."

Lorraine has been remembered for her contribution to the horror genre by the actress who played her in The Conjuring, Vera Farmiga. On Friday, Farmiga tweeted that Lorraine had “touched [her] life".

“From a deep feeling of sorrow, a deep feeling of gratitude emerges,” Farmiga said. “I was so blessed to have known her and am honored to portray her. She lived her life in grace and cheerfulness.”

My dear friend Lorraine Warren has passed. From a deep feeling of sorrow, a deep feeling of gratitude emerges. I was so blessed to have known her and am honored to portray her.
