If everything you see, hear and feel in lucid dreams is the same as when you're awake, how do you know you're dreaming? Can you confuse lucid dreams with reality? What is the objective difference?
Rebecca says: Great question. This is a common misapprehension about lucid dreaming and I'm more than happy to set the record straight.
In my experience (and, I'm sure, the experience of many lucid dreamers) it is not possible to confuse lucid dreams with reality. With the power of conscious thought behind you, knowing you're dreaming is as intuitive as knowing you're awake.
Any deviation from that truth would be an indication of psychosis, and I see no evidence whatsoever to tar lucid dreamers with that brush!
In fact, this myth of confusing dreams with reality stems from a common misunderstanding that lucid dreams can "feel" exactly like waking life. People think that if this is so, then the two states must be indistinguishable.
While conscious dreams can FEEL real, there are other factors, such as memory and logical thought processes, which clearly distinguish these states.
To illustrate this I have mapped out three separate states of awareness - waking reality, lucid dreams and normal dreams - as I experience them:
So while lucid dreaming is a conscious experience, it's a completely different state from being consciously awake, and it is easy to distinguish so.
How Do I Know This Isn't Real?
Philosophical arguments aside (what if reality is a dream itself?) here's a more specific example from last night's lucid dream and why I couldn't possibly confuse it with reality. There's nothing special about this example and I believe you could apply all the same rules of logic to any other lucid dream.
In my dream, I was standing on a mountain over a forest. The desire to fly made me realize I was dreaming. I became lucid and the scenery shot into focus - suddenly I could see thousands of pine trees as vividly as real life. I got a sense of how high up I was, and now, when I looked into the distance, I could see the shiny silvery sea. If it looked so real, how could I be sure I wasn't awake?
But, you might argue, this scene was too fantastical to confuse with reality. So what if I dreamed lucidly of a very boring and lifelike scenario...?
Lucid Dream vs Reality
My experience of being in my living room in a lucid dream is not the same as my experience of being in my living room in reality.
The lucid dream version is self-contained. I can only hear things in the immediate vicinity or whatever my consciousness is focused on.
I don't necessarily know what day it is, nor what time of day.
The world beyond the living room doesn't exist yet until I go there. As a result, I tend to perceive only my localized bubble of awareness and there can be little room for separate lines of thought that don't directly manipulate my dream reality.
And of course, the big giveaway is, in a lucid dream I can do impossible things like push my own fingers through my hand (see: reality check). However, this is typically used to distinguish a dream from reality, and not the other way around.
Indeed, 95% of the population goes to sleep every night and fully accepts their dreams as reality. It's only when they wake up they realize it wasn't real.
In this sense, you can confuse normal dreams with reality, can you not?
But there is no concern for a sane mind to become locked in the belief that they are lucid dreaming, when in fact they are awake.
A final word on false awakenings - aka dreaming of waking up.
These can be exceptionally realistic dreams, like the most vivid kind of lucid dream, and yet you still don't know you're dreaming. Because you dreamed of waking up, you naturally assume you are now awake. Confusing, much?
A false awakening has all the characteristics of a lucid dream (vivid, intense, self-awareness) without realizing you're dreaming or taking conscious control. It is a good example of a scenario where you can confuse a dream with reality based on it's tangible and realistic nature.
The worst case scenario in a false awakening is you get up, get dressed, eat breakfast, head out the door for work... only to wake up, back in bed again. This next awakening can be a false awakening, too. And so it can be a frustrating cycle.
The answer is to perform a reality check when you wake up. Often this transforms a false awakening into a lucid dream!
And while for some people the experience may frustrating as it plays out, I don't believe there is really any doubt of reality when you finally do wake up for real. Objective thought will reveal whether you are dreaming or not... and the only reason a false awakening persists in the first place is because dreams lack objective thought.
This is the key to distinguishing your reality for what it is - and it's automatically provided by a healthy human consciousness.

Books are a powerful way to increase our understanding and generate new perspectives. Good books are immersive and profound: they can change the way we live our lives. In teaching us new lessons, stripping away fallacies and inspiring independent thought, the following books on lucid dreaming are bestsellers for a reason - they are groundbreaking and thought-provoking reads to expand your awareness and develop your lucid dreaming skills.
Galantamine is best known for its ability to improve memory and provoke intense lucid dreams. Research by Dr Stephen LaBerge has found that taking galantamine intensifies your dreams on many levels, including cognition, lucidity, recall, control, bizarreness and visual vividness. If you want to boost your dream life, and maybe prompt some lucid dreams, it's worth taking the occasional galantamine supplement.
Why write a book about how to "hack" sleep? Well, I've suffered from sleep issues throughout my entire adult life. Sleep was such a tough thing to figure out. It didn't respond to willpower. I could beg and cry and kick and scream to myself to fall asleep, but my body would not listen. Finally, I realized that enough was enough and that I was going to fix this very important area of my life for good, or at least do my best to try. I spent nearly one year constructing a system to improve the quality of my sleep.
Humans are unique in our endless capacity for imagination. According to Steven Mithen, an anthropologist at the University of Reading in the UK, we needed to evolve seven critical mental skills before we could have imagination as we know it. Each of these abilities serve a distinct purpose in their own right, while imagination is the culmination of them all.
This dream starts out pretty violent but then suddenly goes all profound on me. I'm having a nightmare in which a thin, gray-faced man is trying to kill me. I become lucid and battle him with ease, firing shots of lighting out of my hands and hitting him in the chest. He falls to his knees and I lock him in a gated prison using only my mind. But then my lucid dream evolves into a lucid nightmare. Another villain, who looks like Krang (or Krang's body at least) from that delightful cartoon about giant mutant turtles, frees the gray man using his telepathic powers. I am no match for him.
Experts agree that everyone is capable of having lucid dreams. Dreaming itself is a normal function of the mind. We all dream every night, even if we don't remember. And we all achieve conscious awareness while awake every single day. So what does it mean to combine these states? Why, the amazing ability to have conscious - or lucid - dreams. Sounds simple, doesn't it? So why do I keep hearing from people who say they can't achieve their first lucid dream?
