What is Precognition?
Precognition is the ability to see in the future. Like most mental abilities, the use and effects of clairvoyance greatly varies depending on the user. Sometimes it is only expressed in vague dreams while asleep, othertimes it is clear and occurs at will and when awake. For instance, Destiny and Hourman see into the future in completely different ways, though both of them are considered to have a form of precognition.
