No one seems to be sure where they came from, but the hotel is well known for having a top floor and basement completely infested with angry spirits. In fact, pets aren't allowed to stay in the rooms on the top floor, because they invariably begin to get out of control.

Route 666 -

Of all the stories that have come out of Route 666, one of the most unsettling comes from a man who was driving by himself down a lonely stretch of road when he saw a truck, engulfed in flames, hurdling toward him. He veered off the side of the road, and the flaming truck continued speeding down the road.

Unfortunately, Cook was a pariah in his hometown, too, and the local church only agreed to bury his body if his grave remained unmarked. This fact seems to anger Cook, and locals say you can see him standing at the edge of the church's property (not pictured), seething with rage.

So, of course, they had to build some. Throughout the whole construction process, Phillips could witness the building of the gallows from his prison cell, eventually causing him to become anxious to the point of a fatal heart attack. Ever since Phillips' death, locals swore they could hear his footsteps anxiously pacing around his cell.

The headless ghost of the Spanish governor -

One of the oldest ghost stories to take place along Route 66, long before it was Route 66, starts in the 1600s in Santa Fe, New Mexico. It all began when the Spanish governor of Santa Fe fell in love with a local woman and sought the help of two witches, who brewed him a love potion to give to the woman.

By the time the governor, Juan Treviño, got back to his love, she had married another man and the love potion was ineffective. Treviño marched back to the witches and demanded a refund. When they refused, Treviño attacked them, and they then proceeded to confiscate his sword and behead him with it. Since that day, his headless ghost has wandered the deserts of New Mexico, searching for his skull and the witches who took it from him.
