Dream themes

Why do you still dream about school and exams years later?

Dream researchers think an old classroom scene returns when a similar pressure does, years later (Picard-Deland & Nielsen, 2021). These dreams have no fixed meaning, and they’re very common: 67.1% of 1,181 Canadian students had dreamed of school and 45.0% of failing an exam (Nielsen et al., 2003). We found no evidence that a bad exam dream predicts how a real test will go.

How often do grown-ups dream of tests and classrooms?

Plenty of adults dream of tests and classrooms, though the biggest surveys asked students (Solomonova et al., 2021; Nielsen et al., 2003). Among 1,181 first-year students at three Canadian universities, “school, teachers, studying” was the fourth most reported of 55 themes (67.1%), and women (71.3%) reported it more than men (56.9%). Nielsen et al. also found that 59.5% had dreamed of arriving too late and 45.0% of failing an exam.

Adults keep having these dreams (Solomonova et al., 2021). In a 2020 survey taken during the first COVID-19 lockdown, of 968 people with an average age of 52.5, 21.2% had dreamed of school, teachers or studying in the past week alone, 12.1% of failing an exam and 33.0% of arriving too late. Dreams of not managing to do things, which the researchers call inefficacy, were the most common topic of all, reported by 62.4%. That group takes in failing an exam, arriving late and trying again and again to do something.

Why would a test you finished decades ago come back?

Dream researchers think an old exam returns because recurring themes work like ready-made scripts (Picard-Deland & Nielsen, 2021). The same script can be reused whenever a similar feeling comes back. That’s why someone facing stress or a new challenge may dream of turning up unprepared for a math exam, years after leaving school. Such dreams can fade for years and come back with a new source of stress, as our guide to recurring dreams explains.

That fits what researchers call continuity: what fills your days and your mind tends to turn up in dreams, though researchers have called it too vague in its general form (Schredl & Hofmann, 2003). Over 6 to 10 years in 28 people, lower well-being went with more negative emotion in dreams and, to a lesser degree, more failures and misfortunes (Pesant & Zadra, 2006). Our guide to how stress changes your dreams has more on this.

Does a bad exam dream mean you’ll fail the real one?

We found no evidence that a bad exam dream means you’ll fail. Of 2,324 students facing a French medical school entrance exam, 719 answered a survey, and 60.4% of them had dreamed of the exam the night before (Arnulf et al., 2014). In 78% of those dreams something went wrong, mostly being late or forgetting answers, yet dreaming of the exam went with better scores. Students who dreamed of the exam more often during the term also scored slightly higher. It’s one study of students who chose to answer, with a small effect, so it doesn’t show that a bad dream helps you pass.

Exam stress doesn’t always reach dreams (Delorme et al., 2002). In one study, 35 female undergraduates kept dream diaries for ten days before exams and for ten exam-free days. The stressful stretch had no consistent effect on their dreams, either in how often the exams appeared or in negative emotion, though 22 of the 35 had dreams that took in the exams.

Which explanation of exam dreams has the most evidence?

No idea about exam dreams has been proven, and some have barely been tested.

Which questions help with a recurring test dream?

Look first at how the exam went wrong. Try these:

• What subject or room was it, and which school?
• What went wrong: were you late, unprepared, lost, wrongly dressed or unable to read the paper?
• Where in your life are you being judged or measured right now?
• When did the dream last come back, and what was happening that week?
• How did you feel when you woke: panic, relief or irritation?

Notes kept over a few months can show whether the dream tracks your busy weeks, and our list of questions to ask about a dream has more.

Is a recurring exam dream anything to worry about?

An exam dream that comes now and then is one of the most ordinary dreams there is (Nielsen et al., 2003). One that wakes you in fear counts as a nightmare (American Academy of Sleep Medicine [AASM], 2020). The AASM treats nightmares as a sleep disorder when they come often and keep you from restful sleep. If disturbing dreams often wake you and you struggle to get back to sleep, the AASM advises talking to your doctor or seeing a sleep doctor.

A nightmare that repeats can sometimes be rewritten while you’re awake (Picard-Deland & Nielsen, 2021), and our guide to changing a recurring nightmare shows how.
