Six Ways to Alter Your Dreams
It's rare that I have an exciting or fun dream. Two-headed monsters or the ability to breathe underwater rarely come up when I'm sleeping. The most interesting dream I've had recently involved me returning to my college job as an ice cream scooper and muttering to a coworker,"Man, this sucks! "It sure did.
Yet many of my friends tell me fantastic nighttime tales of flying all over the world or of scandalous encounters with Clive Owen on a train. I've heard that it's possible to control the course of our dreams via lucid dreaming, but I always assumed that it was an innate ability. In fact, anyone can learn to take the reins from the subconscious and alter dream situations. Using a variety of techniques, we can turn mundane dreams into fantasies that make it even more exciting to crawl into bed.
1. Dream Journaling
A good place to start the lucid dreaming process is to keep a record of previous dre, ams. There are numerous ways to remember your dreams, but one of the easiest and most popular is to keep a dream journal. Put a notebook and pen next to your bed and immediately upon waking write down everything you can remember from your dreams. If writing is too much effort so soon after snoozing, try a voice recorder instead. The point is to keep track consistently so that yore" dream recall improves over time. After all, what's the point of lucid dreaming if you can't remember it in the morning？
2. Mnemonic Induction of Lucid Dreams (MILD)
This technique, created by psychophysiologist Stephen LaBerge, stresses the recognition of dreaming while it's in process. Begin by making it a goal to wake yourself up when yon notice that you're dreaming and chronicle everything you can remember about the dream. As you're falling back asleep, focus on re-entering your previous dream, but this time direct yourself to explore the dream instead of waking yourself up. Keep that awareness as you fall into REM sleep (the sleep stage during which lucid dreaming most commonly occurs). It might help to state aloud, "I am aware of my dream state," as you drift off.
Look for indications-also called dream signs-that alert you to the fact that you're dreaming. These could be anything that are out of the ordinary or would be impossible in real life (the previously-mentioned two-headed monster, for example). This technique can take a while to master, but with steady practice, you can learn to recognize dream signs while still in the dream state, thereby putting yourself in control of the situation.
3. Reality Testing
Reality testing requires constant attention to the world around us-both in dreams and in real life. When going through your day, perform. small checks to determine if what you're seeing is possible in reality. The answer will usually be yes since yon know you're awake (and it'll probably feel silly at first), but the repeated questioning will set your mind up to take the same actions in dreams. For example, something simple like a car not starting is often overlooked in a dream because that's something that could happen in real life. But if a spouse's hair is blonde instead of brown, that's a clear signal for someone using reality testing that he or she is actually dreaming, and this knowledge allows more control over the course of the dream. To get into the habit, set an alarm or make it a goal to do reality checks a certain number of times per day. The checks are a way to teach yourself to notice out of the ordinary occurrences in dreams so that you can reach that coveted awareness without fully waking up.
4. Wake-Initiation of Lucid Dreams (WILD)
Those who use the WILD method to achieve lucid dreaming must learn to stay at least somewhat conscious (but not too conscious, since that might keep you awake) as your body moves into deep sleep. According to the L
A．Seeing a two-headed monster.
B．Being an ice-cream scooper.
C．Being able to breathe underwater.
D．Meeting Clive Owen on a train.

Sleep
Sleep is one of those funny things about being a human being -- you just have' to do it. Have you ever wondered why？ And what about the crazy dreams, like the one where a bad per son is chasing you and you can't run or yell. Does that make any sense？
Characteristics of Sleep
When we see someone sleeping, we recognize the following characteristics:
If possible, the person will lie down to go to sleep.
The person's eyes are closed.
The person doesn't hear anything unless it is a loud noise.
The person breathes in a slow, rhythmic pattern.
The person's muscles are completely relaxed. If sitting up, the person may fall out of his or her chair as sleep deepens.
During sleep, the person occasionally rolls over or rearranges his or her body. This happens approximately once or twice an hour. This may be ,the body's way of making sure that no part of the body or skin has its circulation cut off for too long a period of time.
In addition to these outward signs, the heart slows down and the brain does some pretty funky things.
In other words, a sleeping person is unconscious to most things happening in the environment. The biggest difference between someone who is asleep and someone who has fainted or gone into a coma is the fact that a sleeping person can be aroused if the stimulus is strong enough. If you shake the person, yell loudly or flash a bright light, a sleeping person will wake up.
Who Sleeps？
Reptiles(爬行动物), birds and mammals(哺乳动物)all sleep. That is, they become unconscious to their surroundings for periods of time. Some fish and amphibians reduce their aware ness but do not ever become unconscious like the higher vertebrates do. Insects do not appear to sleep, although they may become inactive in daylight or darkness.
By studying brainwaves, it is known that reptiles do not dream. Birds dream a little. Mammals all dream' during sleep.
Different animals sleep in different ways. Some animals, like humans, prefer to sleep in one long session. Other animals like to sleep in many short bursts. Some Sleep at night, while others sleep during the day.
Sleep and the Brain
If you attach an electroencephalograph to a person's head, you can record the person's brainwave activity. An awake and relaxed person generates alpha waves, which are consistent oscillations at about 10 cycles per second. An alert person generates beta waves, which are a bout twice as fast.
During sleep, two slower patterns called theta waves and delta waves take over. Theta waves have oscillations in the range of 3.5 to 7 cycles per second, and delta waves have oscillations of less than 3. 5 cycles per second. As a person falls asleep and sleep deepens, the brain wave patterns slow down. A person deep in delta wave sleep is hardest to wake up.
REM Sleep
At several points during the night, something unexpected happens -- rapid eye movement(REM)sleep occurs. Most people experience three to five intervals of REM sleep per night, and brainwaves during this period speed up to awake levels. If you ever watch a person or a dog experiencing REM sleep, you will see their eyes flickering back and forth rapidly. In many dogs and some people, arms, legs and facial muscles will twitch during REM sleep. Periods of sleep other than REM sleep are known as NREM(non-REM)sleep.
REM sleep is when you dream. If you wake up a person during REM sleep, the person can vividly recall dreams. If you wake up a person during NREM sleep, generally the person .will not be dreaming.
You must have both REM and NREM sleep to get a good night's sleep. A normal person will spend about 25 percent of the night in REM sleep, and the rest in NREM. A REM session -- a dream -- lasts five to 30 minutes.

For any animal living in the wild, it just doesn't seem very smart to design in a necessary eight-hour period of near-total unconsciousness every day. Yet that is exactly what evolution has done. So there must be a pretty good reason for it!
