The term 'Sense of Disquiet' can be described as a feeling of unease or anxiety, and is often associated with the German word 'ANGST', which has five letters. This feeling of unease can be caused by a variety of factors, such as fear of the unknown, fear of failure, or fear of the future. It can also be caused by a lack of control over one's life or environment. The feeling of disquiet can be overwhelming and can lead to feelings of depression, helplessness, and hopelessness.
