The idea of the existence of ghosts more than likely goes back well before recorded history. They've been brought up in the plays of Shakespeare in the 16th and 17th centuries as well as the plays and myths of the Ancient Greeks dating back to around 700 BC. It can be assumed as primitive humans tried to make sense of the world around them, a lot of strange natural occurrences were probably assumed to be the work of some natural force or another.
Fast forward to today and these ideas really haven't disappeared at all. Many individuals claim to be visited by the spirits of loved ones. Many even believe the strange occurrences that went on in the infamous Amityville home to be true to this day. There are several reality television shows like Ghost Hunters, Ghost Lab, and Most Haunted that attempt to investigate the cases of haunted structures all over the globe.
In 2013, the HuffPost/YouGov did a poll to see how many Americans believe in ghosts. The answer was nearly 45% of Americans believe in ghosts of some kind. 41% of Americans believe they have actually seen ghosts. If you're in a room with three people then at least one of you will more than likely believe to have seen a ghost. Knowing this, it should come as no surprise that even some Hollywood celebrities believe in ghosts and have stories of their own encounters with the paranormal.
10 Sir Patrick Stewart
While performing in Waiting For Godot at the Theatre Royal Haymarket, Sir Patrick Stewart was thrown off during his performance with friend and co-star of the upcoming X-Men: Days of Future Past, Sir Ian McKellen. When McKellen asked Stewart what it was that threw his performance off, Stewart replied with, "I just saw a ghost. On stage, during Act One." Stewart described the apparition as wearing a beige coat and twill trousers.
Cameramen were unable to get pictures or video of the ghost but theater workers believed it to be John Baldwin Buckstone, a playwright and actor/manager of the theater in the 19th Century. Buckstone died peacefully in his home of an illness but theater legend states that Buckstone haunts the premises nevertheless.
9 Keanu Reeves
Keanu Reeves experiences with an earthbound soul are two-fold. One in his childhood and on in adulthood. Of the former, Keanu claims he is still haunted by the ghostly image (in his dreams) to this day.
When Keanu was a child living in New Jersey, he and his nanny both claimed to have seen a ghost. The ghost appeared before him as a white, double-breasted suit. Reeves is reported as saying, "It was a double-breasted suit in white and I looked at my nanny, who was just as shocked as me. I just couldn't get back to sleep afterwards. I still see the figure in my dreams and nightmares."
Later in life, Keanu claims he was having lunch with a friend in Austin, Texas. When he turned around he claims a ghostly image was standing behind him. Keanu hasn't said whether or not he believes it to be the same entity.
8 Matthew McConaughey
The star of the critically acclaimed True Detective not only believes in ghosts, but is also of the impression that they find him irresistible while in the nude.
7 Miley Cyrus
In Miley's London apartment things took a turn for the weird almost instantly. She claims it began with strange dreams and things culminated from there.
In one instance, Miley's sister was showering and she claims the hot water knob turned to max on its own. Miley witnessed that her sister's skin was "really red" and appeared burned. On a later date when Miley was taking a shower, she says that she turned to the bathroom sink and to her surprise saw a little boy sitting on it, kicking his legs and watching her shower.
6 Michelle Williams
The first encounter was three months after Ledger's tragic passing. Williams says she awoke at 3 AM to furniture being moved around her room. When she took a closer look it appeared to be the work of a shadowy figure that looked like it could have been Heath's silhouette.
The second encounter was much more personal. Williams says Ledger apologized to her for not being able to help raise their daughter Matilda.
5 Alyson Hannigan
One might find it mildly humorous that two stars that made names for themselves in supernatural dramas, Alyson Hannigan and husband Alexis Denisof (Buffy the Vampire Slayer and Angel, respectively), would come to purchase a haunted house.
Alyson's ghost was first spotted by one of her friends when her friend claimed that a man had followed them out of Alyson's home. The How I Met Your Mother star wasn't scared by the news at all. She was just pleased to know if she did have a ghost at least he was chivalrous and let the ladies go first.
Alyson has seen the ghost since. On another occasion she thought she saw the silhouette of husband Denisof standing in a doorway. She soon realized Alexis was sleeping right next to her.
4 Dan Aykroyd
There is really no limit to the extent of which Ghostbusters actor Dan Aykroyd believes in the paranormal. He even sells a vodka that is bottled in glass recreations of the famed Aztec Crystal Skulls.
Aykroyd claims he once owned a Hollywood home that was haunted by Mama Cass Elliot of American Folk-Rock group the Mamas and Papas, as well as a man who died on and was buried on a hillside near the home. On one occasion he says he spooned with a ghost in his bed. He believed the ghost to be the spirit of the man that was buried on the hillside. In an interview with Esquire, Ayroyd jokes that "I'd be surprised if I was his type, but when you're dead, you'll take what you can get."
Aykroyd also says he experienced doors opening and closing on their own, as well as items moving across his counters.
3 Kate Hudson
When Kate Hudson was asked if filming her supernatural thriller Skeleton Key changed her views on ghosts and the paranormal, her reply was, "It didn't because I've always believed in spirits and [the] supernatural and ghosts. I've always believed in that stuff."
Hudson has told Betty Confidential that she's been visited by a faceless female ghost "more times than she can count." Hudson also claims on the DVD extras for Skelton Key that she was once visited by the spirit of her grandmother. When describing the feeling she says, "...I woke up and felt amazing that she was around me."
2 Peter Jackson
Before the director went on to do The Lord of the Rings and The Hobbit trilogies, he had made a little ghost movie known as The Frighteners. Peter's encounters with ghosts would not be relegated to his films.
Jackson says that he was once staying in a Wellington apartment when he saw a menacing ghostly woman. He told Britain's Channel 4 TV that he had seen the ghost of a screaming woman with an accusatory face. She then glided across the room and disappeared through a wall.
When Jackson told his wife Fran that he had seen the ghost, Fran described exactly what Peter had seen. She had seen the same ghost in the same room two years prior.
We've saved the weirdest for last.
During an interview with Conan O'Brien, Ke$ha told the late night television host, "I did go to the bone zone with a ghost."
Ke$sha went on to clarify that she didn't actually have sex with the ghost, but merely it was just a "sexy time."
She claims her "sexy time" with the ghost was the inspiration for the song "Supernatural" from her album Warrior. As she would tell Ryan Seacrest on his radio show, "The theme of the record is magic."
