Before the days of surveillance cameras, there was no visual evidence available to see what happened before or after a crime or baffling event took place.
However, surveillance videos often raise way more questions than they answer.
In recent years, many CCTV videos that have surfaced provide a frightening look into the final moments of a person’s life, or a glimpse into paranormal realms.
It’s the kind of stuff that gives some people nightmares.
One of the creepiest mysteries caught on film is the unexplained death of Elisa Lam. Her corpse was discovered floating inside a hotel’s rooftop water tank. The elevator security footage taken of her moments before she died never fails to send chills down our spine.
