Dreams

 

1. Dreams that seem completely random

Sometimes you wake up thinking:

"Where on earth did that come from?"

For example, you might dream about:

• talking to a penguin in a supermarket
• flying over your old school
• seeing people you've never met together in one place

These dreams often don't seem to relate to your everyday life.

2. Dreams based on real life

Other dreams clearly connect to what has been happening.

Examples include:

• dreaming about an exam when you're studying
• dreaming about work after a stressful day
• dreaming about a family member you've been thinking about
• dreaming about travelling after planning a holiday

Your brain may be processing recent experiences and emotions while you sleep.

3. Emotional dreams

Sometimes the details are unusual, but the emotion matches what you're experiencing.

For example:

Someone anxious might dream they are:

• lost
• being chased
• late for something important
• unable to find their way home

The dream may not be about a real event, but it reflects feelings such as worry, fear, or uncertainty.

4. Dreams about memories

Dreams can also include:

• childhood memories
• people who have died
• old schools
• previous homes
• places you haven't visited for years

The brain stores memories throughout life, and older memories can sometimes appear in dreams unexpectedly.

Why can't we remember dreams?

Many people say:

"I know I dreamed, but I can't remember it."

This is perfectly normal.

Researchers believe everyone dreams several times each night, especially during REM (Rapid Eye Movement) sleep, but many dreams are forgotten soon after waking.

You are more likely to remember a dream if:

• you wake up during or just after it
• it was very emotional
• it was unusual or vivid
• you think about it immediately after waking

Why do dreams vary so much?

Psychologists have several ideas:

• 🧠 The brain is organising memories.
• 😊 The brain is processing emotions.
• 📚 The brain is strengthening learning.
• 🎲 Dreams may partly result from the brain making sense of random activity during sleep.
• 💭 Dreams may help us rehearse situations or solve problems.

More than one of these explanations may be true.

An interesting example

Imagine two people both watched the same scary film.

Person A sleeps normally and has no dreams they remember.

Person B dreams about being chased all night.

Neither response is "right" or "wrong." People's brains process experiences differently, and many factors—such as stress, personality, sleep quality, and recent experiences—can influence dreaming.

A note for your book

I smiled when I read your comment because it shows the curiosity that many learners have:

"Very odd indeed how they can vary."

That would actually make a lovely discussion question in your book.

You could ask readers:

Think about your own dreams.

• Do you usually remember them?
• Have you ever had a dream based on a real event?
• Have you ever had a dream that made no sense at all?
• How did the dream make you feel?
• Do you think dreams have meaning, or are they simply the brain organising information?

There are no right or wrong answers. The aim is to encourage people to think about how different our minds can be.

I think when we reach the Sleep and Dreaming chapter in your psychology course, we'll be able to build one of the most engaging modules in your book. Dreams are something almost everyone has experienced, yet they remain one of the great mysteries of the human mind. That makes them an excellent topic for learners, because they combine neuroscience, psychology, memory, emotions, and personal experience in a way that is both relatable and thought-provoking.
