* Sounds, such as footsteps, women and children screaming, doors slamming, and the sound of a blade being sharpened.
* Walls and ceilings bleeding. Attacking them causes more effusion.
* When casting a spell, the player character's body above the waist violently explodes.
* Appearance of large numbers of monsters that are not really there, and disappear when attacked.
* The player character's head falling off. When picked up, the head begins to recite Shakespeare (specifically, Act III, Scene I of Hamlet).
* Character or monsters shrinking or growing.
* A version of the blue screen of death.
* Statues and busts turning to look at the character. They turn back to original position when the character faces them.
* Character whimpering and babbling to him or herself.
* A "to-be-continued" message and promising continuation in a sequel game: Eternal Darkness: Sanity's Redemption.
* Character walking into a room from a previous or future chapter that uses the same location.
* When trying to save, instead of the usual "Do you wish to overwrite saved data" screen, there is a "Do you wish to delete all save files" with the options "Yes" and "Continue without saving." No matter what you do, all files appear to be deleted.
* The word "VIDEO" appearing in the top-right corner in green text on an otherwise black screen, mimicking the "video" channel setting on most televisions when the game system is turned off.
* Game suddenly stops responding to player's commands just as the player-character enters a room full of zombies. The screen displays an error message claiming that the controller has been disconnected. Meanwhile, the zombies attack and kill the helpless character.
