Why do I keep having the same dream?
Recurring dreams are common. They are usually tied to something that keeps worrying you by day or to feelings you haven't processed yet, and they are not omens. If a recurring dream makes you afraid to sleep or affects your days, it is worth talking to a doctor or mental health professional.
What research says
Most dream content continues the people, events and worries you care about while awake (Domhoff, 2003). Something you can't put down tends to come back night after night.
In a study where 32 people logged their dreams and daily experiences for 14 days, more emotional or stressful experiences were more likely to show up in dreams (Malinowski & Horton, 2014).
One explanation for recurring chase or attack dreams is threat simulation: the dream rehearses how to respond to danger in a safe setting (Revonsuo, 2000).
Dreams contain more negative than positive emotion, and anxiety is the most common (Hall & Van de Castle, 1966). Having unpleasant dreams does not mean something is wrong.
How ancient Chinese texts saw it
Wang Fu of the Eastern Han sorted dreams into ten kinds, including dreams born of thought and dreams born of one's state of mind. To him, a dream that keeps returning would mostly come from what occupies the mind.
The Liezi says: what we think by day, we dream by night. People noticed the link between dreams and daytime worries a very long time ago.
When to talk to someone
How often people have nightmares is linked to daytime distress and stress; frequent nightmares that cause worry are a signal worth paying attention to (Levin & Nielsen, 2007).
If a recurring dream makes you afraid to sleep, leaves you exhausted, or your mood stays low, please talk to a doctor or mental health professional. Readings on this site are for entertainment and are not a substitute for professional advice.
What you can try yourself
When you wake up, note what happened in the dream and how you felt. Then think about what in your recent days made you feel the same way. Finding that link is often more useful than asking what the dream predicts.
