Lucid Dream

Dreams are wonderful things. Within a dream, nothing is impossible and the mind unleashes its full potential creativity. Is there a way to harness such power? The short answer is: yes.

Lucid dreams are defined as the state of being aware that you are in a dream. This means that unlike normal dreams, you know that you are dreaming. Although this may sound easy, it is quite hard to enter and stay in a lucid dream. Many people experience a lucid dream a few times in their life, but tend to pass it off as a normal dream or some paranormal event (many “out-of-body” experiences can be explained as lucid dreams).

The major difference between a normal dream and a lucid dream is the ability to control your dream. This concept is explored in detail in the movie Inception, where characters utilise the creative power of dreamspace, tricking the victim that they are in reality to manipulate information out of them. Inception is actually a great example of what a lucid dream is like: the architect can manipulate the dreamspace to her wishes, even going as far as ignoring the laws of physics and conjuring objects out of nothing. This ability is not exclusive to movies – you too can exert this power within your own dreams, every night.

The most important point to remember is that lucid dreams are based on memory. Reason being, if you cannot remember the dream, then it might as well not have happened. Also, you need the ability to distinguish a dream from reality, as otherwise it will pass you by without you realising. There are a few tips and tricks that can help the induction of a lucid dream.

Firstly, keep a dream diary – a record of every dream you have in excruciating detail. This not only trains your ability to remember dreams in detail, but also lets you prepare for when a lucid dream comes. So every morning when you wake up, record whatever you can remember from the night’s dream. Many people complain that they never dream, but this is false – they are merely forgetting it. After keeping a dream diary for at least a couple weeks, you will find that the frequency of dreams increase dramatically, with increasing creativity.

Secondly, look for dream signs. You will notice from your dream diary that certain things appear often in your dreams. This may be a certain person, an impossible object (such as the staircase from Inception), meeting a deceased person or something happening (e.g. falling). A classic example is a clock. In a dream, when you look at a clock (preferably digital) and blink, time suddenly leaps around, such as 3pm suddenly becoming 6pm. Looking for these signs in your surrounding can easily alert you to the fact that you are dreaming.

Lastly, do reality checks as often as possible. These are actions that confirm that you are in reality, or conversely if the check fails, that you are dreaming. Reality checks are represented as totems in Inception, and although the risk of “getting lost in a dream” is close to nothing in a lucid dream, it is an extremely useful tool. Reality checks (RC) are based on the fact that the laws of reality do not function in dreams. For example, a common RC is bending your fingers backwards. In real life, your fingers will only go back so far. In a dream, the fingers can touch the back of your hand: a definitive proof that you are not in reality. Other examples include breathing through a pinched nose, pinching yourself (no sensation in a dream) and… anything creative actually. The general rule is: “habituate what is not your habit” – i.e. make a habit of something that is not usually your habit, so you can do it in a dream as a RC.

After a few weeks practising using the above skills, prepare your mind for a lucid dream. Every night before going to sleep, keep thinking “I will dream” or “I will stay awake in my dream”. Continuous reinforcement directly increases your chance of “waking up” in your dream, and allows you to begin your journey into lucid dreams.

As mentioned above, within a dream, you have almost godly powers as you can manipulate the entire dreamspace to your will. However, there is a catch: you have to control the dreamspace. This may sound absurd, but it will be relevant when you have your first lucid dream. Dreams are like wild mustangs – they will spiral out of control as soon as you try to take control. For instance, a novice lucid dreamer (or, in Greek, oneironaut) will find that as soon as they acknowledge that they are in a dream, they will instantly wake up. This is a form of defence mechanism as the boundary of reality and dream is faded, causing your brain to become confused.

There are methods to help your stay in dreamstate. It has been suggested that when you notice signs of waking up (e.g. the surroundings become blurred and slowly disappear), spinning on the spot can prolong the dreamstate. Rubbing your hands together also helps. The duration you stay in the dream becomes longer as you become more proficient in lucid dreaming.

This is only the first step. The more you manipulate your dream, the more your brain will “reject” your dream-self. Again, this is seen in Inception (it is actually quite an accurate depiction of lucid dreaming). You will find that through practice, you not only lengthen your lucid dream, but also increase the power to manipulate things. In the advanced stage, you will not only be able to completely recreate the world around you, but also achieve flying and the ability to summon people.

A final point to learn about lucid dreaming is that there are two ways into a lucid dream: DILD and WILD.
The first, and the most common, type is Dream-Induced Lucid Dream. This is by far the easiest method. In DILD, you “wake up”, or become self-aware, in a dream and then continue to dream the same dream (except now it is lucid). It is easier to achieve this during a nap or when you go back to sleep after waking up in the middle of the night.

The second, and more advanced method, is the Wake-Induced Lucid Dream. WILD is when a lucid dreamer can go straight into a lucid dream from a state of alertness. This lets you enter a lucid dream anytime at will, and can be more powerful than a DILD. However, there is a catch. WILD easily induces sleep paralysis (see Sleep Paralysis) due to the forced induction of REM paralysis. This can be a horrifying experience for the unprepared, especially due to the nightmarish hallucinations it brings. But after practice and the correct mindset, you can easily vanquish this state with willpower, and freely enter a lucid dream. Sleep paralysis should not deter you from attempting lucid dreaming, for it is only a temporary side effect.

Lucid dreaming is one of the most useful skills one can learn. Not only does it let you explore your mind freely, you can go deeper to discover your subconscious (often through imagery), solve complex problems you couldn’t in real life and relieve the stress built up from reality. An interesting feature about dreams is that time is completely relative; this means you will enjoy a lengthy dream much longer than your actual sleep, giving you a better rested sleep. If you are lucky, you may even enjoy the delightful experience of a “dream within a dream” (or go even deeper).

Oneironauts, dream on.

Sleep Paralysis

Sometimes just before you fall asleep, or just after you wake up, it is impossible to move any muscles. The panic caused by this sudden paralysis is soon followed by a sense of impending doom and unknown horror. When trying to look around to figure out what is happening, you see a ghost or demon sitting on your chest, pinning you down.
This is a typical scenario of sleep paralysis. It occurs when the mind wakes up before the body (in loose terms) and is experienced by everyone at least once throughout their life. 

Sleep is divided into two phases: REM (rapid eye movement) sleep and non-REM sleep. These two phases cycle to make up sleep at a 1:3 ratio (i.e. about 90 minutes non-REM, 30 minutes REM, repeat). NREM sleep is often thought of as “shallow sleep”, but this is incorrect as the third phase of NREM is literally “deep sleep”. This is followed by REM sleep, characterised by relaxation of muscle tone and the eyes darting in all directions (rapid eye movements). The brain cuts off motor signals to the body during REM sleep to prevent it acting out the movements in a dream (without this, many people would injure themselves or others during sleep). For example, patients suffering from diseases such as Parkinson’s disease with REM sleep disorder show vigorous movements during sleep, often hitting their partners in the process.

The problem occurs when the onset of REM atonia (relaxation) comes before the person fully falls asleep, or fails to disappear after waking up. As the motor system has been shut down, the muscles cannot be moved yet the person has regained consciousness. The more frightening thing is that sleep paralysis is usually accompanied by an intense visual and auditory hallucination, which is almost always related the person’s worst nightmares and fears. This explains why so many cultures associate it with demons and ghosts, and it is also possibly the cause of alien abduction experiences and ghost sightings. Reason being, the hallucination is so vivid the person easily believes that it actually happened.

Sleep paralysis can be caused by excessive drinking, stress or the induction of lucid dreams, but tend to be spontaneous and can happen to you on any day.
