Premonitions are psychic visions of future events. I experience psychic premonitions in my dreams and in my waking hours. I can and do have premonitions at any time, but more usually when I'm meditating, conducting rituals or when Spell casting.
Although I do see some visual pictures and sometimes hear things in my psychic premonitions, it is more about the feelings and emotions I experience that compel me to pay attention. These are glimpses I have into the future and should not be ignored.
Prophecies, are as the word suggests, predictions about the future usually made by prophets. These prophecies are usually profound utterings that have major influence on world events. Throughout history prophets have made profound prophecies that, after time, have proved to be correct. Along with the religious prophets, others have been heralded as prophets.
Nostradamus is probably the most prolific prophet who correctly prophesised the Great Fire of London in 1666, details of the French Revolution, the rise of Napoleon and Hitler, twentieth century earthquakes, John F. Kennedy's assassination, Princess Diana's untimely death, man's landing on the moon and even the 9/11 terrorist attacks.
