BEING A TEACHER....

BEING A TEACHER IS A DIFFICULT TASK NOWADAYS, SO I DECIDED TO FOLLOW THIS PIECE OF ADVICE BY BRUCE LEE:

Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water, my friend.

Can we record dreams?


Here are some interesting articles to read, listen and watch:

  1. I’ve read this article and I think that it’s a very interesting project and a breakthrough for the science and the medicine, since we will be able to comunicate with people who have mental diseases like commas, and maybe, find a medicine to trate these problems.
    Another use could be to improve people’s memory or intruce in people’s minds a lot of information that could be useful for studying.

    On the other hand, in my opinion, this project has a lot of obstacles too. Do we really want that people can read our minds when we walk in the street or when we go shopping, for example? If this project is realised, probably, we wouldn’t have privacy anymore. The people might know our secrets or what we are thinking about somebody. It’s a huge topic to discuss, because in the future if we do this, we’ll be like robots created by humans.

  2. Why do we dream?

    We do not understand why we dream and it is difficult to carry out research as 95% of dreams is forgotten and many people forget their dreams within the first 10 minutes of having them.

    In 1952 scientists discovered REM sleep. This means Rapid Eye Movement, and it is a stage in sleep when there is a lot of brain activity, accompanied by rapid eye movement. During REM certain chemicals are released that block the body's muscles, so we can dream about flying and fighting Ninjas, but our bodies don't move. Some people's brains do not allow the release of these chemicals and so their bodies move when they dream; they can even sleep walk!

    There is a connection between REM and memory. If you deprive people of REM sleep they can become disorientated and their memory begins to fail. This works the opposite way as well, if you learn a new activity during the day, like playing a musical instrument, during the night the brain reenacts the electrical impulses reenforcing the learning. Perhaps Alberto could use this to improve our English by letting us have a short nap during classes!

    But why do we dream?

    Scientists differ in their answers, some think that what dreams are about is the reorganization of our memories and the strengthening of connections from the day before. As the conscious brain receives these electrical impulses, it tries to interpret them and make a sort of cohesive narrative, but only dreams are made. Dreams are therefore an accidental result of the more important process that is going on in our brains.

    Other scientists, however, believe that dreams have a purpose and that purpose is to prepare us for threats. The most prevalent emotions experienced in dreams are negative, such as, anger and anxiety. They believe that when we were early humans we had no idea what sort of threats we might encounter during the day, so in preparation our bodies would simulate anxieties while we slept in order to prepare us for the threats in real life.

    Nobody really knows however, and even for the scientists dreams remain a mystery.

  3. Most of the time we do not remember what we dream. Some people say that dreams are nothing more than images that form in our brain during the night to resolve internal conflicts that we have not had the courage to face consciously during the day.

    Others, however, assure us that we do not usually remember what we dream because memory is so busy building a dream that, in the end, they forget to store it.

    The truth is that a person before entering the deepest phases of sleep, known as slow wave dreams, usually presents four or five periods of very short dreams at the beginning of the night and longer towards the end.

    The duration of one of these dreams lasts between 90 and 120 minutes in adults (and around 8 hours in children). Numerous studies have shown that it is very common to wake up a few seconds before one of these dreams ends.

    If we approach these people at that moment we can observe how during this phase their eyes move quickly, since the activity of brain neurons is similar to when the person is awake. At that precise moment, if we asked them, they would probably remember what they had just dreamed. But, if we let them go back to sleep until the next morning, they would not remember anything anymore because the dreams are not stored in the memory.

  4. Dreams take place while we are asleep. It is recommended to sleep around 8 hours in adults and 9 hours in children. Both of them have dreams in this period of time, although children dream more than adults. It is strictly verified.

    Dreams are shapes and actions that do people or animals in your brains while you are sleeping. One curiosity of dreams is that you can only dream with faces that you have seen in your real life.

    The 95% of the dreams are not remembered by the persons, and they usually think that they are not dreaming anything but it is not true, everybody dreams.
    Other point of dreams are that we remember and we think it will to happen but it is not real.
    Many people have usually nightmares, that are bad dreams, one example of nightmare is the death of a loved one or the death of oneself are the most commons.
    We also have more than one dream in a night.

    Because of don't remember the dreams many scientist have thought about an invent to know what have you dream or know what are you thinking in any moment. I think it could be a big evolution for the science because it couls improve the medicine to people with mental diases but I wouldn't like that anyone read my mind and know what I think.

    From my point of view dreams are neutral for us it does not apport anything except if they are nightmares. On the other hand I think that read the minds would be useful to the medicine or to the mental diseases but no to read the mental diseases.

  6. Have you ever had a crazy dream or a beautiful dream ?. Do you dream very often?. We know that we only dream while we are sleeping and when we wake up , most of the time we can´t remember the dream we had, but why does this happen ?.

    Dreams are experiences that happen in our brain where images are mixed together with sounds and sensations . These images can become so real that sometimes they can confuse us . Some people say that they don´t have dreams , but this is not true because scientists think that we all dream , but many times we forget them . Some people who have dreams remember only a part of it or they don´t know exactly what happened.

    American researchers want to record dreams electronically. They developed a system that can record a higher level brain activity . A study by the team suggests that the activity of individual brain cells , or neurons , is associated with specific objects , for example , when a volunteer was thinking of an actor , a particular neuron lit up . And this is how scientists could interpret dreams.

    As far as I´m concerned , a dream is something very personal, but without importance because most of the time they don´t have specific meaning.

  7. Sleeping is one the activities that we have to do if we want to stay active all day. Sometimes when we are sleeping we have dreams or images that try to show us or alert us about something. But, what is the purpose of our dreams?

    Since the beginning of time, humans has been fascinated by dreams and have tried to find meaning for them. Moreover, dreams interpretations have been present along the history. Dreams are images or sounds that our brain creates when we sleep.

    Most of the time people who dream do not remember what they dreamed. Many times we are dreaming something interesting and suddenly we wake up and then we try to remember it but we can´t. We can dream with anything and if sometimes the dream seems very real is because our unconscious tries to tell us something.

    In conclusion, dreams have been present all the time. We usually dream of something that we can not remember but that probably has a meaning.
