Journaling

How do you find patterns in your dreams?

To find patterns in your dreams, tag each entry with its people, places, events and main feeling, then count how many entries share each tag, month by month. A pattern is what keeps coming back across many entries, not one striking dream. It can show what’s on your mind (Domhoff, n.d.), but it can’t tell the future or diagnose you.

What counts as a pattern in a dream journal?

A pattern in a dream journal is something that repeats across many entries: the same people, places, situations or feelings. It differs from a recurring dream, where one dream comes back again and again. Patterns are personal: we found no study showing that a symbol means the same thing for everyone.

What repeats can stay steady for years (Domhoff, n.d.). The dream researcher G. William Domhoff studied one woman’s journal of 3,116 dreams kept over more than 20 years. When his team compared the earlier and later halves of a random sample of 250 of her dreams, they matched within 5 or 6 percentage points in all but two or three categories.

How do you tally what repeats across your entries?

Tallying starts with tags. After each entry, add three to five: the people, the place, an object that stood out, what happened, and the main feeling with how strong it was. Rate the feeling yourself: when outside judges scored people’s diary dreams, they underrated the good feelings, while the dreamers’ own ratings showed good and bad in balance (Schredl & Doll, 1998). Tagging is quicker when every entry uses the same fields, like those in the dream journal template.

At the end of the month, count how many entries each tag appears in, and turn the count into a share of that month’s entries. A share lets you set a month of 30 entries beside a month of 12. Watch the length of your entries, though. In Domhoff’s (n.d.) case study, the share of reports with at least one social interaction, such as a friendly or hostile exchange, rose with report length up to about 400 words. Percentages within a category, such as the share of all characters who were friends, held steady once reports reached 50 words. So compare months whose entries run to a similar length, or compare shares within one category, as in the friends example.

A digital journal makes counting faster. A word search with 40 categories turned up many of the same patterns in classic dream collections that earlier researchers had found by hand, one dream at a time (Bulkeley, 2014). Keyword searches of one person’s dreams can also track characters, activities and emotions (Domhoff & Schneider, 2008b).

How many entries do you need before a pattern means anything?

A pattern needs more entries than a few weeks usually give you. In one diary study, averaging over two weeks and only a few dreams limited what the researchers could detect (Schredl & Hofmann, 2003). Telling one person’s dreams from another’s generally takes samples of 100 to 125 reports, because most things in dreams appear in fewer than half of reports and the differences are usually modest (Domhoff & Schneider, 2008a).

Domhoff’s (n.d.) case study points the same way. Any 125 of the 250 sampled dreams matched the overall results almost exactly, but samples of 100 strayed often, and samples of 75 or 50 strayed much more. These are research thresholds, so treat them as a rough guide at home. A single vivid dream doesn’t make a pattern. Compare one month with the next, and give a larger pattern several months.

What can your dream patterns show you?

Dream patterns can show what’s on your mind (Domhoff, n.d.). In Domhoff’s case study, much of the dream content echoed the dreamer’s waking thoughts and concerns. That was especially true of the most important people in her life and her strongest interests, worries and fears, often played out as worst-case scenarios.

Everyday routine may appear less than you might think (Schredl, 2021). In that study of 12,476 dreams one man recorded between 1984 and 2016, clocks appeared in 0.74%, and the clocks he owned in waking life very rarely, though he used an alarm clock in the morning. Schredl suggests that things we do over and over may not show up in dreams very often, and that novelty or emotional weight may affect what does. Like Domhoff’s case study, this series comes from a single dreamer, which Schredl (2021) names as the main limitation of his study.

What can’t your dream patterns tell you?

Dream patterns can’t tell you the future, and they can’t diagnose you. We found no good evidence that a pattern in dreams predicts events, and only a doctor can say whether frequent bad dreams point to a health problem (AASM, 2020).

Your own reading can bend the counts. People give more meaning to dreams that fit what they already believe (Morewedge & Norton, 2009). Domhoff (n.d.) notes that most dream analyses are tailored to what is already known about the dreamer, which is why his team coded the dreams without knowing whose they were. At home, the nearest step is to tag entries first and decide what the counts mean later. Then bring the tags that repeat most to your questions about a dream.

Keeping the journal also changes what you record. Over two weeks, a dream diary raised recall for people who usually remembered few or a moderate number of dreams, and lowered it for those who usually remembered many (Schredl, 2002). Daily logs also caught more bad dreams than people had estimated from memory (Robert & Zadra, 2008).

When does a dream pattern mean it’s time to talk to someone?

A dream pattern is a reason to talk to someone when bad dreams start costing you sleep or spilling into your days. The American Academy of Sleep Medicine (AASM, 2020) advises talking to your doctor or a sleep doctor when disturbing dreams often wake you, bring fear, anger, sadness or disgust, and make it hard to fall back asleep. The AASM counts nightmares as a sleep disorder when they come often and keep you from restful sleep.

If nightmares are the pattern, the guide to nightmares covers what helps; if darker dreams line up with a hard stretch at work or home, see how stress changes your dreams.
