Pulled this from a review of Silent Hill: Shattered Memories for Wii. 

Finding the source of this disturbance will lead to a spooky moment and the receipt of an eerie voicemail or text message on your cell phone, which helps to explain the significance of that particular localized haunting. Occasionally, you may also catch a glimpse of a ghostly flickering image just out of focus to the naked eye but not to the digital sensors in your camera phone--snapping a photo reveals the hidden truth and also triggers the delivery of a voicemail or text. In Shattered Memories, the town itself is a main character, and everything from the haunted objects to the kitschy mementos you find lying around help to establish it. You can even call up the phone numbers seen on billboards and wanted ads all over the city for hidden messages.
