Dream Dictionaries: What They Get Right, and What They Miss
You wake from a dream of losing your teeth, reach for your phone and search for what it means. Within a minute you have a confident answer. By the third site you have three different confident answers. Dream dictionaries are very popular and quite unreliable as a source of single meanings. But they are not useless, and it helps to know where their value lies.
What dictionaries get right
Across cultures and centuries, people report remarkably similar dream themes. Researchers who catalog dream reports, such as the psychologists Calvin Hall and G. William Domhoff, found that falling, being chased, being unprepared for a test and strong emotions recur everywhere. A dictionary that collects these common images is tapping something real: people do share a few dozen common dream scenes.
Dictionaries are also good at offering vocabulary. Having a few possible readings to choose from can help you put words to a feeling that you might not otherwise describe. In that sense an entry works like a tarot card: a prompt for reflection.
What they miss
Context. A dream of a dog means one thing to a person bitten as a child and another to one who has just adopted a puppy. No dictionary knows who you are.
Emotion. The feeling in the dream is usually the best clue. A snake that frightens you and a snake that fascinates you are different dreams with the same image. Good interpreters start from the feeling.
Ordinary causes. Many dream images have simple explanations that a dictionary skips: a full bladder produces water dreams, a hot room produces fire dreams, a real noise gets woven into the story and grinding your teeth may produce dreams about teeth.
The idea that every dream is symbolic. Some dreams seem to be straightforward replays of the day, called continuity dreams. Not every element needs to be decoded.
What sleep science adds
Most vivid dreaming occurs during REM sleep. Researchers disagree about why we dream. Some argue that dreams help consolidate memory, and some that they rehearse responses to threat (an idea sometimes called the threat simulation theory), and others that they are a by-product of the brain’s activity during sleep. No leading theory says that specific images have fixed meanings. What the evidence does support is that dreams tend to reflect waking concerns, including stress, recent events and emotions.
A better way to use a dictionary
- Write the feeling first. Before anything else, note how the dream felt.
- Note the circumstances. What was on your mind yesterday? What are you anticipating this week?
- Rule out the physical. Were you too hot? Did you need the bathroom? Was there noise?
- Then read two or three readings of the main image, in our Dream Dictionary or elsewhere, and ask which one, if any, connects to your situation.
- Do one small thing. If the dream pointed at something you have been avoiding, do ten minutes of it.
Recurring dreams
A dream that keeps returning is usually tied to something unresolved or to a persistent feeling, often anxiety. Keeping a dream journal for a few weeks tends to reveal the pattern, including what tends to precede the dream. If a recurring dream is distressing, particularly if it follows a difficult event, talking to a therapist or doctor is better than searching for its meaning. Repeated nightmares are a treatable condition.
Dreams and astrology
Dreams are not an official part of chart reading, although the Moon and the twelfth house are traditionally linked to the subconscious, and Neptune to imagination. Some astrologers track the Moon’s sign and phase against their dreams. Since there is no evidence that they matter, treat it as a reflective habit. A notebook and five honest minutes each morning will tell you more about your dreams than any list.
