Which word implies a feeling that something is about to happen, often in a negative context?

The word "premonition" specifically refers to a strong feeling or intuition that something, often unpleasant or negative, is about to occur. This term conveys a sense of forewarning or an unshakeable sense of impending doom, which fits the context of the question perfectly. While excitement and anticipation can both indicate a sense of looking forward to future events, they typically carry positive connotations and do not imply an impending negative event. Sympathy, on the other hand, relates to feelings of compassion or understanding towards others' suffering rather than indicating a foreboding feeling. Therefore, "premonition" is the most accurate choice for conveying that ominous feeling of an event that may unfold unfavorably.
