One story I heard was about a first responder who entered a supposedly haunted house. As he walked through the dark corridors, he felt a cold hand on his shoulder but when he turned, there was no one there. Another time, a paramedic reported seeing a strange figure while attending to an accident victim in a desolate area. The figure seemed to be guiding him to where the victim was hidden from view.
There was a firefighter who was called to an old, abandoned building on fire. When he entered, he heard whispers that seemed to be warning him about unstable structures. He later found out that the building had a history of tragic deaths. And in a different case, a rescue worker at a flooded area saw a glowing figure leading him to a family trapped in a cellar.
Well, I know of a police officer who was patrolling a cemetery at night due to some reports of vandalism. He saw a misty shape floating among the tombstones. At first, he was scared but then he noticed that the shape was leading him to a group of teenagers who were about to do some damage. This was really strange as it was as if the supernatural entity was helping him do his job.
