Premonition refers to a situation when future events are foreknown or forecast. They are attribute by some people to the presence of supernatural or paranormal abilities.(see Cassandra myth). However, the distinction between precognition and ordinary evidence-based predictions is sometimes not made sharply. "Premonition" may be defined to include or exclude ordinary predictions, and this means a fallacy of linguistic ambiguity can lead to an overly supernatural explanation for the accuracy of predictions.
