Twins are obviously very close. They share not only genes but friends, bedrooms, and even secrets. But might it be possible that they share thoughts-without even opening their mouths? Many twins-as many as 20%-claim to share something far more mysterious: a special psychic connection. Take the case of Gemma Houghton. In 2009, she had the strange feeling that her sister Leanne desperately needed her help. So she walked upstairs to the bathroom, where she found Leanne unconscious in a bathtub full of water. She had suffered a seizure had nearly drowned. Fortunately, Gemma arrived in time to save her sister. But as inexplicable as this may seem, perhaps it's not so mysterious after all. Leanne had had seizures in the past and Gemma had been warned to watch out for her. Knowing that it was dangerous for Leanne to be alone in water, it's not surprising that Gemma might have become concerned for her after a few minutes of hearing no activity from upstairs. It's likely that any other family member would have acted just as Gemma did.
