Is a feeling of imminent but unclear threat?

A feeling of imminent but unclear threat often manifests as anxiety or heightened alertness without a specific source of danger. This sensation can stem from various factors, including stress, environmental cues, or past experiences. It may lead to a sense of dread or unease, prompting individuals to be on guard despite not knowing what they are reacting to. Such feelings can be challenging to manage, as they create a constant state of tension without a clear resolution.
