1. Is it possible to directly into a person's dream?

In inception, dream experts using a drug called somnacin and a machine, a consciousness to upload to someone's dreams.Then, several dream experts themselves will also fall asleep, dream through the machine into the target.This fictional dream machine is known as "carrying type automatic Somnacin iv" (hereinafter referred to as PASIV).

In fact, can effectively read brain devices already exists.For example, functional nuclear magnetic resonance (MRI) scanner, can capture photos of brain activity, and then through the software reproduce the image of volunteers are seeing.One day, the researchers said, functional magnetic resonance imaging (mri) scanner may to record of someone's dream, at the same time, there is no the sharing dreams like in the movie describes the trouble or danger.

Use drugs, somnacin into someone else's dream is impossible, but some drugs can significantly adjust our sleep, such as modafinil (modafinal), the drug can make people stay awake all the time, there are some new sleeping pills, can let a person into the "super sleep".

2. What can we do to control your dreams?

Want to experience a lucid dream (lucid dream), the simplest way is when you sleep, often train ourselves to ask such a question: "I am dreaming?"Some people obsessed with video games is especially good at doing this lucid dream, perhaps because they focus on several hours every day to accomplish a task.

Inception of dream experts after altitude training, also at it, it may be they can complete complex tasks (read) in a dream of reason, for most lucid dreamers, they are difficult to do this.In inception, some people still can arm themselves in dreams, to prevent other dream expert invaded their dreams.

3. The dream must abide by the laws of physics?

This is a controversial topic, the inception of its is discussed from two aspects: sometimes, something magical happens, for example, in someone's a dream, just like a big piece of paper folded in Paris;Sometimes, some optical illusion becomes "true".Dutch artist, for example, the ritz - kerner, rhys escher (M.C.E scher) creation of endless stairs appears in inception, it is to use like happened in certain operation is completed in a 3 d virtual environment.

But, the dream will follow the law of some "real life".A writer and producer Jeff Warren (Jeff Warren) has described his survey of the dream, no sensory input, conscious behavior seems to become unpredictable.We can launch some informal laws from the dream, such as the "law of self-fulfilling expectations" (what do you expect will happen) and the "law of narrative power" (stay in one place for too long, dream start into a conflict).In inception, for example, when external influences into the real world, dreams "in conflict".

4. What is the function of dreams?

Freud believed that dreams expressed our repressed desires.Sometimes, a dream really had this effect, but more and more modern research has shown that dreams could help information processing and memory storage.Both rem sleep (i.e., shallow sleep), or non-rem sleep (sleep), we all dream.The difference is that in rem sleep mode, dreams more like a story, full of emotion and conflict;And during non-rem sleep mode, the dream usually involves a friendly social interaction.Those depression, for example, tend to experience more rem sleep is rem sleep.

5. The dream of the subjective time is how to go?

In inception, dream of the time is much slower than the real world, but also there is a so-called "scale effect" (scaling effect), or if your dream is a dream, time will be more slow.So, 5 minutes in real life, the dream is equivalent to an hour, and 5 minutes of dreams, and secondary dreams in a week.

This time the dream and the reality of the virtual description may be the nods eyeball pen of inception, however, we besides amazed by the exquisite design of the film, at this stage, and there is no evidence to prove it.In fact, the researchers found in the study of a lucid dream, some evidence, at least when the dreamer woke up, they will feel about time changes described above.

For researchers, a more pressing problem is that when our brain problems of perception of time, what will happen.In fact, although the illusion of time is produced by the brain itself, but as inception in the plot, the same illusion that scientists feel puzzled.
