“There is actually a continuum of these experiences,” Dr. Orepic said. Some recordings contained recorded bits of their own voice, while others had fragments of someone else’s voice or no voice at all. The study found that when people were already experiencing the peculiar feeling of a ghostly presence, they were more likely to say they had heard a voice when there was none. What’s more, hearing a nonexistent voice was more likely if, earlier in the experiment, they had heard bursts of noise with someone else’s voice in them. That suggests the brain was linking the hallucinated presence and the voice, Dr. Orepic said.
