Imagine you’re a butterfly, fluttering around and following your whims. Then, suddenly, you wake up. But how can you be sure you’re not dreaming right now? While the answer might seem obvious, it’s actually quite challenging to explain how you definitively know you’re awake. This question has puzzled philosophers for centuries.
The ancient Chinese philosopher Zhuangzi introduced an intriguing idea: if we can dream of being an entirely different creature, like a butterfly, who’s to say we’re not actually a different creature dreaming of being human? In dreams, strange things happen—you might fly, conjure an all-you-can-eat dessert buffet, or get chased through familiar places that suddenly look different. Yet, these oddities don’t seem strange while you’re experiencing them.
So, how can you be sure you’re not in a dream right now that will seem odd once you wake up? Some people experience lucid dreams, where they are aware they’re dreaming. However, realizing you’re in a lucid dream doesn’t confirm that you’re awake. There needs to be a reliable test—something that only happens when you’re awake or only in a dream.
Common suggestions include trying to wake up, pinching yourself to see if it hurts, or attempting to read or write something. You might also run around the room to assess your pace—does it seem normal or unusually slow or fast? If you’re unsure, try to remember the last time you ran.
This brings us to a more sophisticated test from the 17th-century French philosopher René Descartes. He noted that in our memories, dreams are often disconnected—the events of a dream don’t fit into the sequence of our waking lives. For example, you couldn’t have swum with dolphins in a dream if you never left your hometown, and you have the evidence to prove it.
However, Descartes’ contemporary, the English philosopher Thomas Hobbes, questioned this: what if Descartes was performing his test in a dream? Even consulting a neuroscientist to measure brain activity could be part of a dream.
So far, no one has found a convincing answer to this dilemma. Yet, there’s a lot more detail in our waking experiences than in dreams. We go to sleep and wake up again day after day for many years, and each new day is filled with countless people, places, and experiences. Even our memories, which capture just a fraction of this experience, contain an almost incomprehensible amount of detail. We can recall a line from a favorite book decades later, remember the musty smell of its pages, and the taste of the lemonade we drank while reading it.
Isn’t it hard to believe that a dream could ever simulate this richness? As the Persian philosopher al-Ghazali pointed out, just as we think we are awake after dreaming, it’s possible that we might wake from our current state into another state of even greater awareness. This would imply that we’re in a kind of dream state when we think we’re awake.
What philosophers really want to know is what justifies our belief that we’re awake. We all want to believe things for good reasons, not just because they seem right. Sometimes, the biggest challenge is to explain why we should believe something that seems completely obvious to us.
Engage in a class debate on the topic: “How can we be certain that we are not dreaming right now?” Divide into two groups, with one arguing that we can be sure we’re awake, and the other arguing that we cannot be certain. Use examples from the article and other philosophical ideas to support your arguments.
Keep a dream journal for a week to record your dreams. Try to identify any patterns or signs that indicate you are dreaming. Discuss with your classmates how these signs could help you determine if you are dreaming or awake, and relate this to the concept of lucid dreaming mentioned in the article.
Perform a series of reality checks throughout the day, such as reading a text, checking the time, or pinching yourself. Reflect on how these activities feel and compare them to your experiences in dreams. Share your findings with the class and discuss how these checks might help you distinguish between dreams and reality.
Create a timeline of your day-to-day activities for the past week. Include as many details as possible. Compare this with a dream you remember vividly. Discuss with your peers how the richness and continuity of waking life differ from the fragmented nature of dreams, as described by Descartes in the article.
Write a short story inspired by Zhuangzi’s butterfly dream. Imagine waking up as a different creature and explore the philosophical implications of your new reality. Share your story with the class and discuss how it relates to the themes of perception and reality explored in the article.

You’re like a butterfly, fluttering around and following its whims. Then you wake up. But how can you be sure you’re not dreaming right now? The answer may seem obvious, but it’s actually quite challenging to explain how you definitively know you’re awake. This question has puzzled philosophers since ancient times.
In the butterfly scenario, the ancient Chinese philosopher Zhuangzi raised an intriguing possibility: if we can dream of being an entirely different creature, who’s to say we’re not actually a different creature dreaming of being human? Strange things happen in dreams: you might fly, conjure an all-you-can-eat dessert buffet, or get chased through familiar places that suddenly look different. However, the oddities of dreams don’t seem strange while you’re experiencing them.
So how can you be sure you’re not in a dream right now that will seem odd once you wake up? It is possible to notice the strangeness of a dream while you’re dreaming. Lucid dreamers are aware they are dreaming. But this only proves you’re not having a lucid dream; it doesn’t confirm that you’re awake. There has to be a reliable test—something that only happens when you’re awake, or only in a dream.
You might think to wake up, but you can wake up in a dream. Pinching yourself might seem like a good idea—if it hurts, aren’t you really awake? Trying to read or write something could be another test. Running around the room might help you assess your pace—does it seem normal or unusually slow or fast? If you can’t tell, try to remember the last time you ran.
This brings us to a better test from the 17th-century French philosopher René Descartes. He noted that in our memories, dreams are often disconnected—the events of a dream don’t fit into the sequence of our waking lives. This seems solid, right? You couldn’t have swum with dolphins in a dream if you didn’t leave your hometown, and you have the evidence to prove it.
However, one of Descartes’ contemporaries, the English philosopher Thomas Hobbes, questioned this: what if Descartes was performing his test in a dream? We could consult an expert—a neuroscientist could measure brain activity and tell you whether you’re awake or asleep. But this just circles back to the idea that any test you might use to prove you’re awake could also occur in a dream.
So far, no one has found a convincing answer to this dilemma. Yet, there’s a lot more detail in our waking experiences than in dreams. We go to sleep and wake up again day after day for many years, and each new day is filled with countless people, places, and experiences. Even our memories, which capture just a fraction of this experience, contain an almost incomprehensible amount of detail. We can recall a line from a favorite book decades later, remember the musty smell of its pages, and the taste of the lemonade we drank while reading it.

What philosophers really want to know is what justifies our belief that we’re awake. We all want to believe things for good reasons, not just because they seem right. Sometimes, the biggest challenge is to explain why we should believe something that seems completely obvious to us.

Dreaming – The process of experiencing thoughts, images, or emotions while asleep, often explored in philosophy as a way to question the nature of reality and consciousness. – Philosophers like Descartes have used the concept of dreaming to question how we can be certain of our reality.
Philosophy – The study of fundamental questions about existence, knowledge, values, reason, mind, and language through critical, systematic approaches. – In philosophy class, we debated whether free will truly exists or if our choices are predetermined.
Reality – The state of things as they actually exist, as opposed to how they may appear or might be imagined, often a central topic in philosophical inquiry. – The philosopher’s quest to understand reality often leads to discussions about perception and truth.
Memory – The faculty by which the mind stores and remembers information, playing a crucial role in forming personal identity and understanding past experiences. – Philosophers often explore how memory shapes our understanding of self and continuity over time.
Awareness – The knowledge or perception of a situation or fact, often considered a key component of consciousness and self-reflection. – Developing awareness of our biases is essential for critical thinking and philosophical inquiry.
Experience – The knowledge or skill acquired by a period of practical involvement in an activity, often used in philosophy to discuss empirical knowledge and personal growth. – John Locke argued that all knowledge is ultimately derived from sensory experience.
Belief – An acceptance that something exists or is true, especially without proof, often examined in philosophy to understand knowledge and faith. – Philosophers debate whether belief requires evidence or if it can be justified by faith alone.
Test – A method of assessing the validity or truth of a hypothesis or belief, often used in philosophy to evaluate arguments and theories. – The philosopher proposed a thought experiment as a test to challenge our assumptions about morality.
Richness – The quality of having a great deal of variety or complexity, often used in philosophy to describe the depth of an idea or experience. – The richness of Aristotle’s ethical theories lies in their comprehensive approach to human flourishing.
Challenge – A call to engage in a contest or competition, or to question the validity of a claim, often used in philosophy to stimulate critical thinking and debate. – The philosopher’s challenge to the prevailing moral norms sparked a lively debate among the students.
