Each and every night, your brain transitions through different stages of sleep.
Each stage has different effects on your body - from physical restoration during deep sleep, to memory consolidation during dreams.
All together, these stages add up to about 90-110 minutes, making up one complete sleep cycle.
We used to identify five stages of sleep (as above) but recently Stages 3 and 4 have been grouped together for their similarities.
Let's take a closer look at those four stages:
Your longest and most memorable lucid dreams usually occur in the fourth and fifth sleep cycles of the night - after about six hours of sleep - during the REM sleep stages. Critically, during these later sleep cycles, periods of REM sleep become longer.
The graph shows REM sleep occurring at the end of each sleep cycle. This is your most memorable dream time.
If you don't wake up to an alarm, you'll find you often wake directly from a dream, which makes it much easier to remember. When this happens - don't move. Just allow yourself to gently re-enter the dream, while thinking "I'm dreaming".
This graph also shows how it's essential for lucid dreamers to get sufficient shuteye and not miss out on REM sleep by cutting sleep short. Indeed, the more chances you have to sleep in, the better. Sleeping-in allows extended REM time in the morning, more vivid dreams, and more chances to become lucid.
So, how much sleep do you meed?
It seems that the amount of sleep required differs from person to person, however as a rough guide experts have come up with the following daily sleep guide based on age:
What's also important is to look at how you're waking up - ie, after how many sleep cycles.
If you wake to an alarm every day, your sleep is likely to be interrupted mid-cycle. This is such a common problem it's known as getting out of the wrong side of the bed. This may also explain why you're not a morning person.
An alarm cuts your sleep short arbitrarily and denies your final REM phase. It's much healthier to wake up after the cycle is complete which is what happens without an alarm.
Fortunately, there is a growing array of sleep tech to achieve this without being two hours late for work every day. These gadgets and apps can track your sleep cycles and wake you only once a cycle is complete.
We can measure the length of dream time using an EEG machine which reads brainwave activity. Dreams are directly correlated to REM sleep - to the extent that your eyes can move and track in the same direction you are looking in the dream.
The brainwave readings tell us that REM sleep at the end of the first sleep cycle lasts only a few minutes. Much of the first cycle is dedicated to non-REM sleep, driven by the need for physical rest. So, these early dreams are often fleeting. You are unlikely to remember them and they're unlikely to yield lucid dreams.
As you sleep on through the night, your REM phases grow longer in each sleep cycle. By morning, your fourth or fifth sleep cycle (ending when you wake up for the day) may allow for 45-60 minutes of uninterrupted REM sleep. It's perfect for lucid dreaming.
Every now and then I hear an urban myth about lucid dreaming that someone had a dream that encompassed an entire lifetime.
I've had such a dream, while taking the dream intensifier, Calea Z. Time seemed to stretch and I felt like I was in this dream for years. But as vivid as the dream was, I didn't literally experience those years, minute-for-minute. It was more like watching an epic movie that spans 200 years in the space of two hours, yet you feel like you were there longer.
Generally, the timeframe of regular dreams are in line with reality. However it's always difficult to judge the length of a dream from the first-hand perspective of dreaming it. Whether you're lucid or not, time can be distorted in dreams - and there are a lack of constants against which you can measure the passing of dream events.
So, if you feel a dream lasted for days or years, it's just your perception of events in the dream that made it seem to last so long. I don't believe that such dreams - however mind-blowing in their realism and adventure - are comparable to the experience of real time passing in the waking world.
Like regular dreams, lucid dreams can last anywhere from a few seconds up to an hour (and possibly even more). For me, a typical lucid dream lasts 10-20 minutes.
Most beginners find their lucid dream collapses within a few seconds because the emotions of becoming lucid are so overwhelming. However with a few simple dream stabilization methods, you can massively prolong your lucid dreams.
As soon as I learned how to prolong my lucid dreams, it opened up a world of possibilities. My dream world posed a new adventure playground, in which I could travel anywhere and do anything I wanted to with complete clarity and awareness. What's more, these stabilization techniques serve to enhance the dream clarity and my ability to control it, while preventing me from waking up prematurely.

Chloe is a natural lucid dreamer. That's to say that all of her dreams are conscious (lucid), highly realistic and incredibly vivid. She can remember these dreams as far back as being a toddler. That level of mindfulness we regular folk strive to achieve in our dreams is always present in her nightly escapades. Her dreams, by default, are highly intense, profound and acutely self aware.
Lucid dreams are a life-changing opportunity for all of us. If you want to learn how to have lucid dreams, this section gives a flavor of the mindset and the techniques you'll learn. I'll be absolutely up front with you. If you're going to learn how to have lucid dreams, you need to inject three things in your life starting today. Time: it takes time to learn a new skill like lucid dreaming. For instance, time to record your dreams each morning. Time to meditate and incubate a self-aware mindset. Time to perform a pre-sleep lucidity routine.
It's the most frustrating thing about lucid dreaming. You finally realize you're dreaming, get excited about the infinite possibilities... and immediately wake up. What's the point of all this lucid dream training if the experience only lasts a few seconds? How much more effort is it going to take to learn how to prolong your lucid dreams? The answer is: none at all.
Learning to have lucid dreams -- it's fun, intensive, frustrating, euphoric, bizarre, daunting -- yet ultimately, lucid dreaming is a hugely rewarding and life changing experience. Learning how to lucid dream is like any other skill that you develop over time. There is no magic secret. But there are a number of tried-and-tested methods that you can employ. Below I've listed a number of those techniques to get you started. Happy dreaming...
This week I was the recipient of a ten-year anniversary gift from Pete (meaning I opened a package with his name on it and was all "Hey cool! Is this for me?!"). The gift was a set of AcousticSheep SleepPhones - wireless headphones embedded in a plush headband which receives audio from your nearest device. The main reason he got this for me was to listen to music and podcasts more comfortably in bed. It's also a top selling product among joggers, air travelers, the partners of snorers, and insomniacs. AcousticSheep SleepPhones have applications in entertainment, leisure, sport and sleep therapy.
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?
