Traveller

This unnamed traveler is a supporting character in Deeper Sleep. A mysterious individual, he is one of countless humans trapped in the dream realm. Unlike many, however, he has no intentions of waking up, instead consciously choosing to stay behind and gather information to ensure he and other travelers do not fall victim to the lurking dangers of the realm.

Deep Sleep
The traveler, while not making a physical appearance, is heard via recording, having apparently taped a message for anyone unfortunate enough to enter the world of dreams, urging them to wake up, to beware of the Night Folk and go to the lighthouse if all else fails. The recorder loops and is transmitted through a phone, the former of which is later turned off by "Yourself".

Deeper Sleep
The player encounters him in person in the basement, behind a sewer grate. The traveler recognizes them, realizes they did not listen and informs the player that it was him that left the player a message about the lighthouse in the previous game. Here, he serves as a source of vital information and lore about the dream realm, such as the Night-Folk, Felicity and the machinations of the world. He also instructs the player to descent into the Deepest Sleep to wake up, but warns them that the further they go, the more likely it is that they are lost forever.

When asked about why he doesn't try to wake up, the traveler claims he'd rather stay in the dreamworld, despite the hazardous environment, admitting that he fears that his life in the waking world is even worse.

Trivia

 * He shares his appearance with the protagonist of A small talk at the back of beyond. Whether this was purposely done remains unconfirmed.
