At me it is developed very strongly and I for a long time understand, as it is necessary and important for people thinking. Sometimes something really unpleasant happened, and sometimes not. That all depends on how much this premonition, and not just what I dreamed myself of something.
In fact, the feeling is a deep analysis of our thoughts. If the analysis is performed correctly then your premonitions come true, if not then you made a mistake in the analysis. It's very simple.
