Waverly Hills Sanatorium in Kentucky was originally opened to treat tuberculosis patients but majority of the treatment didn’t work out. The rate of deaths increased enormously, so much so, that they had to build an underground tunnel to bury the dead bodies. The sanatorium was soon converted into a mental asylum but the patients were still dying due to lack of treatment. More than 400 deaths took place here. Locals and ghost hunters have complained about seeing shadows, hearing disembodied voices and seeing objects move by themselves. It is said that a nurse killed herself on the fifth floor after finding out she was pregnant with a doctor’s baby.

Built in 1935, Old Changi Hospital was initially used as Royal Air Force Hospital but, during World War II it was converted into a Japanese prison camp where people used to be tortured for being anti-Japanese.

Visitors have also complained about hearing disembodied voices and seeing shadows flitting from corners of the room. Some also claim to be pushed by unseen hands. 

This asylum in Australia was apparently home to some of Straya’s most unstable, violent, and tortured criminals.

Local residents claim to hear sounds of children playing around in the area and seeing ghostly apparitions floating around in the corridors. 

Reports suggest that this psychiatric hospital in England tortured patients. It is said that people who were given “treatments” at Severalls weren’t mentally ill at all.

Visitors claim that they have been pushed by an unknown entity on several occasion while others have complained about an eerie sensation like they are being watched by unseen eyes. No one dares to come close to this abandoned building anymore. 

Just like other haunted hospitals, Taunton State also had a creepy past. Here, doctors were apparently given full liberty to do all sorts of inhumane experiments on their patients who were mentally ill.

Some also claim to see shadows crawling up the walls and on ceilings. 

This psychiatry hospital in Asia was taken over by the Japanese soldiers during World War II to house prisoners of war. During the war, it was apparently also used as a execution ground.

Now, this hospital is commonly known as the ‘Ghost House on High Street’ by the  locals.
