Feeling trapped, frightened or overwhelmed in a dream can signify a "bad" dream. These dreams often evoke negative emotions and can leave a lasting impact upon waking. The symbolism within such dreams varies greatly, as the concept of "bad" is subjective to each individual. However, common symbols in these dreams may include dark or foreboding environments, being chased or attacked by a threatening figure, witnessing violence or harm to oneself or others, or experiencing a general sense of terror and unease. It is important to note that interpreting the exact meaning of a "bad" dream relies heavily on personal experiences, emotions, and circumstances. Thus, exploring the specific elements and emotions within the dream can help uncover insights into underlying fears, anxieties, or unresolved issues that may need attention in one's waking life.
