A woman has extremely acute hearing, so much so that she is able to hear her own body fluids moving.
Julie Redfern, 47, has superior canal dehiscence syndrome , which causes her to hear her brain move, her heart beat and her eyeballs squeak.
Redfern works as a receptionist and said the condition is so severe that her vision pulsates with the rhythm of the phone ringing.
"It's very frustrating being able to hear everything," she said. "You think you wouldn't mind and maybe I wouldn't if it was just a bit of gossip but nobody wants to be able to hear their body constantly. The doctors just said, 'it's your age, when you get to 40 these things happen.' I thought I can't put up with this forever, I knew something wasn't right. I could hear my heartbeat and what seemed like all my bodily functions. I could hear even the slightest noise. I could hear things that were louder than they should have been, I could hear myself swallowing and my voice echoing."

She describes the noise in her head as a "swishing."
"Everything moving in my head sounded as though it was swishing away," she said. "When the phone rang at work the vibrations would make my eyeballs shake. I would be standing in the queue at the supermarket and I'd start to sway, I felt drunk without having a drink."
She said she first started hearing her eyeballs squeak after her 40th birthday in 2006.
When she was playing Tetris at home, she heard a squeaking noise and soon realized it was her eyes.

Then, she stopped eating crunchy foods because she found the noise they produced to be deafening.
Redfern believes that she got the condition after a bicycle crash she had in her 20s.
SCDS is a condition of the inner ear that causes a thinning of the temporal bone at the base of the skull. Since being diagnosed, she has had surgery to fill the holes in her bone.
"I always said it was like I needed plugging up," Redfern said. "Fluid from the superior canal was leaking. The surgeon had only performed the operation four times before. He opened me up like a book just behind my ear and described the inside of it like honeycomb instead of being like cinder toffee because of the holes."
Now she just has to get her other ear done and she will hopefully be cured.
"I know when I have the other ear done I'll be cured — but you never know I might miss not hearing all these strange little things," she said.
