Frequency: This is the most common nightmare.

Usual meaning: You are feeling threatened by someone or by a strong emotion of your own. You feel frightened, attacked and in danger. Occasionally your brain may be replaying an actual event in your own life.

Questions to ask yourself:

• Who or what is chasing you? What does it look like — size, color, shape, etc.
• What is its outstanding physical characteristic?
• Of whom does it remind you or who has similar characteristics?
• What happens in the dream?
• How does the dream end?
