Workers at a Costa Rican hospital were mystified when the siren of an ambulance activated on its own and a later check of the security footage from the site revealed an eerie shadow moving away from the vehicle. According to a local media report, the strange incident occurred last Friday evening at a Red Cross facility in the district of Pocosol. As seen in the video below, staff at the site that night were startled by an ambulance's siren that inexplicably came to life. Rushing out to the parking lot to deal with the situation, the puzzled workers found no one in the area who could have been behind the sudden commotion.
