Dread or terror is a feeling of intense FEAR or anxiety. It is often associated with a sense of impending danger or doom. It can be caused by a variety of factors, including physical or psychological trauma, a traumatic event, or a perceived threat. It can also be caused by a combination of these factors. FEAR can manifest itself in physical symptoms such as increased heart rate, sweating, trembling, and difficulty breathing. It can also lead to mental health issues such as depression, anxiety, and post-traumatic stress disorder.
