Do you think you have had a premonition before? How can someone know something is about to happen even before it does? Could it be an event that is paranormal or maybe it is just feelings that we get if things are not exactly right? Premonitions are not believed in by scientists. They only believe in things that they can prove to be facts. They know that there have been reports of people that have had knowledge of events or have had feelings about things prior to it occurring.
