1. Mackenzie Poltergeist in Greyfriars

The Mackenzie Poltergeist is one of the most famous attractions when taking the City of the Dead tour within the Greyfriars Kirkyard in Edinburgh as people who join the tour experience bruises, scratches, and some even faint as they enter and see the Black Mausoleum where Sir George Mackenzie lies. Is it all for show? Maybe there’s only one way to find out…

2. Aluminum Wedge of Aiud

Back in 1974, a group of workers in Romania discovered three different objects 10 meters deep in a sand trench. Two of the items were prehistoric elephant bones that have been dated as old as 2.5 million years ago. The third object however, is an aluminum wedge that was found together with the ancient bones. This discovery dumbfounded most researchers, as aluminum was difficult to create even by 19th century standards. While some call it evidence of extraterrestrials, others are calling it a hoax. Whatever it is, we may never know.

3. SS Ourang Medan

What happened to SS Ourang Medan or “Man from Medan” in Malaysia is perhaps one of the most fascinating and mind-boggling mysteries that ever existed in seafaring history. Everything began with an SOS message in 1947 that mentioned the captain, along with the rest of the crew, was dead. What’s worse, even the telegrapher died during the transmission of the message. When the Silver Star was able to receive the distress call and went to inspect the ship, they confirmed the deaths of all aboard. Speculations of ghosts, hazardous chemicals, and even aliens have been raised, but there is still no conclusion as to what actually happened.

4. Nazca Geoglyphs

The Nazca civilization is responsible for some of the most fascinating geoglyphs on the face of the Earth. They include everything from spiders, monkeys, sharks, orcas, and  flowers, the precision of which is incredible given that the Nazca had no way of examining their work from above.


5. Lal Bahadur Shastri

He died an unexplainable death since he left the country healthy. Many have claimed that he died of heart attack, but the doctors and other specialists who have checked him out, including his wife, confirmed that he was A-okay. His wife had also made the assertion that the Tashkent Pact, upon signature, gave the chance for him to be poisoned. This was never proven since there was no post-mortem diagnosis of the body so every assumption that could be answered were already included in the grave.
