The Plains Hotel, Cheyenne, Wyoming, USA

The Plains Hotel is an imposing building in Wyoming's capital city. It opened in 1911, offering one hundred guest rooms and five elevators - no small feat for a hotel of that time, even in a major city.

It's no surprise that the hotel was a destination for honeymooning couples. One new bride, called Rosie, checked in with her husband on what was to be the last trip of her life.

Rosie's husband (no Prince Charming, he) wandered down to the lounge one evening for a drink or two. Hours later, when he hadn't returned to their room, Rosie found him still in the bar, getting friendly with a prostitute.

Rosie's new husband, with his new friend, left the bar and went to the prostitute's room on the fourth floor. Rosie followed, and with her husband's gun, shot the prostitute, her husband, and (back in the honeymoon suite) herself.

The ghosts of all three parties to the murder/suicide have been seen by staff and guests. Rosie, wearing a blue gown, walks the hallways of the hotel. Laughing and crying have been heard from the room that was once hers. Her husband is seen on the fourth floor, and - oddly - the basement. The prostitute is seen on the second floor.

Kewaunee Inn, Kewaunee, Wisconsin, USA

The Kewaunee Inn (once the Karsten Hotel) is close to Lake Michigan, Green Bay - and the supernatural.

The building turned 100 years old in 2012. In 1966, work was done on the hotel, and it seems that this operation brought out the spirits of three people once attached to the hotel - a former owner, his grandson, and a maid.

Why the maid (Agatha Struck) haunts the inn is a mystery; she was not an owner, and she didn't die on the premises. Rumor has it that she was in love with a former owner; if so, given the fact that they both haunt the place, she may be happy now. She has been seen performing her old duties, such as sweeping the halls. One guest who stayed in 310, Agatha's old room, watched, freezing, as a filmy wraith floated through the wall. She is known to move objects, especially when the inn was renovated in 1984; Agatha showed her displeasure by hiding tools, opening and closing doors, and turning lights on and off.

William Karsten, Sr., has been seen having an ethereal beer in the bar. Like Agatha, he moves things (in his case, furniture) when upset; he also causes a foul odor to show his unhappiness.

Billy Karsten, William's grandson, died of meningitis at the age of five. Living children have played with a little boy on the second floor, a boy who looks strikingly like the photo of Billy. He has also been heard running down the hall to his grandfather's room.

Ross Castle B&B, Oldcastle, County Meath, Ireland

Ross Castle (NOT to be mistaken for a castle in Killarney with the same name) is a rather imposing 16th-century building on Lough Sheelin.

The first owner was Richard Nugent, 12th Earl of Delvin, who had the castle built in 1536. Nugent, who was called "the Black Baron", was so eager to punish crime in his area that he had an innocent man hanged for stealing a loaf of bread (the real culprit was a dog).

In true Romeo-and-Juliet fashion, the Black Baron's daughter, Sabina, fell in love with Orwin O'Reilly, member of an enemy family. After many a secret meeting, the two decided to elope. They set sail across the lake, but a storm blew up and capsized their boat. When Sabina awoke, three days later, she learned that Orwin had drowned. Distraught, she refused food and drink, with the predictable result.

Sabina still haunts her former home; some say that she is being punished for the heartless actions of her father. He has not escaped his own punishment, though; his ghost has been sighted many times.

General Lewis Inn, Lewisburg, West Virginia, USA

The General Lewis Inn features at least three ghosts - a woman in white, a little girl, and a slave.

The inn was once a private home, built in 1834. During the early 1860s, the Civil War took a heavy toll on the area - and may have contributed to the ghost population.

A lady in white (the most popular dress color for ghosts, it seems) haunts Room 208 - fittingly enough, because her portrait hangs in that room.

The little girl has been heard, both crying and laughing, though not simultaneously, in Rooms 206 and 208, as well as Suite 202. Paranormal investigators who slept in the suite reported waking in the night to see a girl in a brown outfit standing next to the bed.

The slave, who is named Reuben, was hanged on the spot where the dining room now stands. He has been seen sitting at the table. Those curious to see him might decide to eat every meal at the inn.

The Queen Mary, Long Beach, California, USA

The Queen Mary was one of the most luxurious ocean liners in the 1930s, transporting movie stars such as Douglas Fairbanks, Jr. and Bob Hope. With the advent of World War II, however, the ship was repainted and used as a troopship. She became known as the "Grey Ghost", a fitting nickname for a ship that would come to be known as one of the world's most haunted.

As air travel increased, the era of the luxury liner came to an end; on Halloween, 1967, the Queen Mary set out on her final cruise, arriving in Long Beach on December 9. She has been there ever since, converted into a hotel.

With ghosts.

One crewman played "chicken" with a watertight door once too often, and was crushed when it slid shut during an emergency (to prevent water from flooding other sections of the ship). He has been seen near the fatal door, usually disappearing near or through it.

During her years as a troopship, the Queen Mary accidentally rammed a smaller ship, causing it to sink. Screams can still be heard in the bow.

The swimming pool in the First Class section is haunted by several female ghosts, many wearing swimsuits in the style of the 1930s.

Cabin B340 is so haunted - sheets flying across the room, faucets turning on and off - that it is no longer used as a guest room.

A cook who traveled in the ship during WWII was such a bad cook that he was stuffed into an oven and roasted. His screams are still audible.

There is also an eerie legend that during the ship's travels of the 1930s, a certain passenger asked a crew member to bring him some "company". Money changed hands, and a young woman was sent to the man's cabin to "entertain" him.

When the man didn't appear at breakfast the next morning, and didn't answer his door, the door was forced open. The cabin was found to be soaked in blood - the blood of the young woman. The man was never found; there was no record of any passenger being assigned the cabin in which he stayed, and no luggage for him was ever found.

Battery Carriage House Inn, Charleston, South Carolina, USA

The Battery Carriage House Inn dates from 1843. It calls itself "Charleston's most haunted inn", and this may be true.

The ghosts are a rather obliging crew, generally staying to their assigned rooms. The most haunted areas are Rooms 3, 8, and 10.

Room 10 is the domain of a specter known as "the gentleman" ghost, who has a liking for the ladies; indeed, one guest reported that she saw a figure float over to her bed and lie down on it with one arm around her! Another woman saw a shadowy form cross the room and fade through a closed door. The ghost is thought to be a 19th-century man who committed suicide by jumping off the roof of the house.

Room 3 has several presences, as witnessed by a couple who stayed there. A light emanated from the bathroom, a cell phone refused to work, and several figures were seen.

Room 8 is one the faint of heart might like to avoid. The ghost is thought to be that of a Civil War soldier. Only the torso appears, usually next to the bed. One brave guest touched the torso (clad in rough material) and the torso made a sound as of raspy breathing. Another guest claimed to have photographed the torso when aiming her camera up at the room window from the courtyard.

Happy hauntings, everyone.

The Feathers Hotel, Ludlow, Shropshire, United Kingdom

According to the New York Times, The Feathers Hotel is "the most handsome inn in the world."

According to other sources, it's one of the most haunted buildings in the U.K.

The building was constructed in 1619 as a private residence (and what a residence!) by local attorney Rees Jones. After the English Civil War, Jones' son Thomas had it converted to an inn. In 1863, The Feathers Inn became The Feathers Hotel - ghosts and all.

- In one room, a man wearing old-fashioned clothing is seen sitting in the window, a dog at his feet.

- An employee, when cleaning a lounge late at night, would hear his named called. He was the only staff member working, each time.

- Footsteps have been heard in the Prince Charles Suite.

- A couple who stayed in Room 212 were unable to remain in the room. The husband left after three hours; the two never said what had happened, but another woman claimed that King Henry VIII was there.

- A woman was pulled out of her bed, by her hair, in the middle of the night. Her husband merely felt someone stroking his face.

- The man with the dog has been seen walking through one of the rooms (in an extension to the hotel, built in the 1950s) and disappearing through the wall.

- A woman has been seen outside the hotel, crossing the street and walking through a parked car. In this case, it is believed that the apparition is that of a living woman - she is wearing the clothing of the 1960s - and that the woman in question is well aware of the appearances.
