You approach Mr. Smith, a look of concern on your face. "What did you mean by 'unusual passengers'? And are we safe here?" you ask.

Mr. Smith nods gravely. "I apologize for any alarm I may have caused. It seems that some...unfortunate souls have found their way onto our ship. They are not like the other passengers, and they do not belong in this world." He leans in closer, his voice barely above a whisper. "They are the spirits of those who have died at sea, trapped between the worlds of the living and the dead. And they are not happy about it."

He pauses for a moment, as if collecting his thoughts. "But do not worry, my dear passenger. They will not bother you. They only come out at night, when the ship is dark and quiet. Just be sure to stay in your cabin after sunset, and all will be well."

You nod, feeling a shiver run down your spine. You had heard rumors of ghostly apparitions on the Titanic before, but you never thought they would affect you personally. Still, you are determined to make the most of your time on the ship, no matter what dangers or mysteries may lurk in the shadows.
