On December 7th, 1941, the Imperial Japanese Navy bombed Navy Base Pearl Harbor (now Hickam Field, formerly and most commonly known as Hickam Air Force Base) to prevent any future attacks on Japan. The bombing led to extreme amounts of damage, aircraft destruction, 189 people killed, and 303 injured. Now, the base is said to be haunted by the 189 lingering souls.
The Pacaf Headquarters building is particularly haunted, with remaining bullet holes from the attack. There have reports of doors opening and closing on their own and the apparitions of dead soldiers appearing in the halls dressed in 1940s uniforms.
