2. Hoover Dam
The Hoover Dam at the border of Arizona and Nevada has a lot of supernatural energy associated with it. This energy is possibly from the numerous souls who lost their lives at this site either by accident or suicide. 112 workers lost their lives over five years during the dam's construction in the 1930s. Recently, a mysterious woman was accidentally caught on camera by a random person. Shortly after, she disappeared after plunging below to end her life. The spirits of the dead make this place creepy, and a feeling of death looms in the area.
