In your level, you might have object you want the player to interact with to get a bit more information or narrative context. For that purpose you can use the prefab PointOfInterest located in HorrorEngine/Prefabs.
Simply position it in your level, adapt the Interaction trigger to cover the interest area and set the dialog lines on the PointOfInterest component.
As part of the dialog setup, a voice over audio file can be assigned to each dialog line to play at the same time the text is shown.
