Typically, if you hear a voice saying something but no one’s around, it’s safe to assume you’re just hearing stuff. But what if multiple people hear it too? This is what happened in Salt Lake City, Utah, on March 10, 2015. After police officers found a car overturned in icy waters, they didn’t suspect anyone inside had survived, according to ABC News. After all, by their estimates, the car had been there about 13 hours, and it looked to have been in a pretty bad accident.

But the three officers and two firefighters who went to check the car heard something chilling — an adult, female voice saying, “Help me.” Assuming that someone in the car was still alive, the men righted the vehicle quickly and set to extracting the survivor. What they found was not what they expected however.

The driver, Jennifer Groesbeck, looked to have been dead for quite a while, probably since the impact. The only other passenger was her 18-month-old daughter in the car’s back seat. She had survived the accident and hung upside-down over freezing water for 13 hours. The rescuers removed the child from the car, and she was sent to a hospital, where she recovered. Despite multiple officials and onlookers on a nearby bridge hearing a woman’s voice, they were unable to determine where it came from.

The U.S. Military Academy, better known as West Point, has trained soldiers for over two centuries and is even a national landmark. The school trains would-be military officers and is full of cadets and the staff who work there. These are people trained to be observant and aware of what’s going on around them. So it’s kinda bananas that West Point Academy is very frequently reported to be haunted.

The school had one particularly famous ghost back in the 1970s that attracted worldwide attention — an apparition of what appeared to be a 19th century cavalry soldier. Sightings of the spirit rippled through the cadets after an on-campus talk by Ed and Lorraine Warren, most famous for their fictionalized selves in The Conjuring movies. According to the New York Times, instructors at the academy ended up needing to close off the room where the sightings occurred, because the ghost was distracting the cadets from their studies.

This is far from the only spirit roaming the halls of the academy, though. As noted on the U.S. Army’s own website, there are numerous other stories of paranormal encounters that cadets and instructors have come across, such as The Lady, said to be the spirit of a sickly woman whose husband carried on an affair with the woman’s mother. Supposedly, The Lady even has some poltergeist-type tendencies, like throwing things around or flipping them over.

Say you lost your keys. You’ve looked everywhere for them but had no luck. Then, your friend says, “I can sense the keys, and they’re in a cold place.” You open your fridge and there they are, right next to the butter. This is a simplified example of the alleged phenomenon of remote viewing. Basically, it’s the ability to see or otherwise gather information about a subject that is not possible for one to actually observe.

While this could be helpful for everyday life, should it be proven to exist, the military has long been interested in remote viewing for strategic purposes. Throughout the 1960s and 70s, the government had sunk a lot of time and money into studying potential applications for psychic espionage. It seems that this only particularly paid off once, though, in 1976.

An administrative assistant working for the CIA by the name of Rosemary Smith volunteered to use her self-proclaimed psychic powers to locate a downed plane in Africa. The agency gave Smith a shot, and she drew maps and provided details about the plane’s crash, according to Annie Jacobsen, author of Phenomenon. Amazingly, the maps turned out to be at least somewhat helpful, as the plane was recovered shortly after. Supposedly, this is the one time in military history that a psychic provided actionable information. Whether it was real psychic powers or pure luck, it seems all of the other research ended in nothing.

While a 61-year-old man reporting an unknown craft close to midnight in some quiet woods between Glasgow and Edinburgh, Scotland, might sound questionable, police took notice on Nov. 9, 1979, because of who the man was — Robert Taylor, a forestry worker who never touched alcohol and had been a respected war hero, according to the BBC.

According to Taylor, while working around 10:30 p.m. at night in Dechmont Woods, he spotted a dome-shaped craft, about 30 feet tall, in a clearing. This might be strange enough, but the craft then ejected two spiked balls that chased him down. Taylor passed out before they reached him, but when he awoke 20 minutes later, the clearing was empty. However, the ground was pock-marked with holes where the balls had rolled toward him, and his pants were badly ripped.

Taylor was so shaken, he crashed his van into a ditch and walked back home, where his wife contacted police. Taylor described what happened to him and they investigated, finding the holes he spoke of and indentations in the ground where the craft would have been sitting — all of which seemed to indicate that an object weighing several tons had been there. While they could find no cause for the marks, police did note that they were localized to that clearing, starting and ending there. As for Taylor’s pants, forensics found that they had been ripped by something hooking into them and moving upward.

Rendlesham Forest, found in Southeastern England, is quiet and fairly isolated, which is exactly why England’s Royal Air Force (RAF) established two bases in the area — RAF Woodbridge and RAF Bentwaters. During the Cold War, however, these bases were used by their allies in the United States Air Force (USAF), and on Dec. 26, 1980, the U.S. forces stationed there encountered something very odd.

At around midnight, an unidentified object was spotted on radar and confirmed visually as well. The object seemed to head into the forest, so a USAF security patrol went to investigate. These men later claimed that they encountered a brightly-lit triangular craft. When they got to close, however, the craft shot up into the air, and the investigatory patrol was knocked unconscious.

Another group sent out to find the initial crew confirmed markings on the ground that seemed to indicate something had landed there, according to HowStuffWorks. The following night, sightings of strange lights began to trickle in. Deputy base commander Lt. Col. Charles Halt decided to investigate firsthand this time, leading a party of fellow airmen into the forest. According to Halt’s story, they encountered high radiation counts and multiple floating lights, one of which flew directly at the group, emitting various colors. While the military supposedly has photos and video of the events of that night, they’ve never been released.
