Book taste linked to dreams: If you like fiction, your dreams are likely to be stranger but you’ll remember them more readily. Fantasy readers have more nightmares and ‘lucid’ dreams. “The research also suggests children who read scary books are three times more likely to have nightmares.” What does ‘suggested’ mean here? The adult findings probably mean that personality type shapes both reading preferences and types of dreams — correlation but not causation. While it is not hard to understand how reading a child a scary story might cause a nightmare, will it shape her personality so that she has a lifelong tendency toward nightmares? I doubt it. BBC
