Rachel Stephens knew there was something wrong with her when she was walking down the street one day and found herself in the middle of the road. She was wearing headphones and on her phone at the time, and looked up to find herself facing cars, completely unaware how she got there.
"My legs just took me there, that is when I knew something couldn't be right, if your body is doing things you aren't aware of, that isn't right," the 29-year-old said.
It was just one of a series of "funny things" that kept happening to her between months of going back and forth to the doctors. Describing another incident, Rachel said: "I was dipping a biscuit into a cup of tea and went to eat it but I kept missing my mouth, I was hitting my cheek with the biscuit. I had to hold my wrist with my other hand to control the movement.
