A feeling of premonition can be described as:

A feeling of premonition refers to an instinctive sense or intuition about what may happen in the future. This kind of feeling often arises without concrete evidence and is more about a gut feeling or an inner sense of forewarning. It implies a kind of foresight, suggesting that someone has an innate understanding or a hunch regarding future events, which aligns perfectly with the notion of intuition.

In contrast, the other options pertain to more structured or analytical processes. A sudden realization of a fact involves understanding something new based on existing knowledge. An analysis of past events requires critical thinking and reflection on previously gathered information, while a rational deduction of outcomes implies a logical assessment based on facts and reason. None of these capture the essence of premonition, which is inherently more instinctive and less anchored in rational analysis or past data.
