"The Arrival" / Paranormal Story Part 1.

  With nothing to do but endure the buttock pain of sitting for hours, he lay down on the table where he used to work and fell asleep in a few minutes. Dominic Diaz had no idea that night was going to be any different than any previous night in his career as a security guard at the New York Museum of Natural History.

---Dom! Help me! Please help me! aarrgh!..---

This time the bewildered guard could see the source of the sound, took the radio transmitter from his waist and carried it near his mouth to respond.

---Tony! What's up, buddy?! You scared the hell out of me!--- He didn't get any answers.

--- Tony!... please answer what's going on... --- the nervous guard said again, as he thought his heart was going to come out of his chest and he felt a drop of sweat begin to descend from his forehead. But what he heard next ended up freezing his blood, causing a real sense of fear in his body. A grim, rough, ghostly voice was heard through the communicator:

---Tony.... No!....! He no longer exists...---

Dominic didn't remember being so nervous in his life --- "Maybe he's playing a joke on me"--- he thought.

    Without turning the matter over too much, and despite the terror he was feeling, the security guard armed himself with courage in addition to his gun and set out down the cold stairs that connected the security quadrant with the main hall of the museum, hoping that it was all just a bad joke on his partner's part.
