Dreams
Nightmare
Definition
A frightening or distressing dream that often wakes the sleeper, usually reflecting stress, anxiety, fear, or unprocessed emotion rather than foretelling anything.
A nightmare is a frightening or distressing dream, often vivid enough to wake you with a racing heart. Despite centuries of folklore treating bad dreams as omens, the grounded view is that a nightmare reflects your own mind at work — usually processing stress, anxiety, fear, or an emotion you haven’t fully resolved.
Read honestly, a nightmare is a signal rather than a sign: it dramatises a feeling you’re carrying, which makes it worth reflecting on, not fearing.
