Consciousness is a very interesting aspect of brain study. While we sunbathe on a warm sunny day, we recognize sensations outside our body. The sun shining down, in addition to sensations we feel like muscles relaxation. Past this fundamental awareness, we are additionally aware of ourselves having these encounters. Analysts define consciousness as the awareness we have of nature’s domain and ourselves.
The level and state of consciousness contrast. States of consciousness are associated with different brain wave forms. Brain waves are detectors that show the electrical activity functioning in the brain. Scientists utilize an electroencephalograph (EEG) to record different types of waves. There are four central types of brain waves. Alpha

Sigmund Freud assumed that dreams let people to fulfill unconscious desires. He thought that a dream has meaning. Activation-synthesis suggests that neurons within the brain arbitrarily actuate throughout Rapid eye movement (REM) sleep. Dreams rise once the cortex attempts to create sense of those impulses. Some researchers think that dreams precise people’s most persistent concerns and might help to resolve problems in daily life. If someone has an important job interview coming up, for instance, he or she may prepare circumstances for the interview in dreams. If someone has relationship complications, his dreams may give him clues to help resolve the problem. Some analysts suppose dreams categorize people’s most pressing issues, whereas others suppose dreams arise throughout the brain’s routine housekeeping chores such as eliminating or cleaning up neural networks. In lucid dreams, people are conscious that they are dreaming and may be able to control their actions to certain extent in the …show more content…
People meditate to improve consciousness and gain more physical and mental control. Methods used in meditation differ and encompass activities such as breathing training and repetitive chanting. Through Meditative states alpha and theta brain waves increase, and physical meters of relaxation such as slows down pulse and breathing. Researchers have discovered that meditation has long-standing effects such as improving physical and mental health and reduction of stress. Nevertheless, some scholars disagree about whether meditative states are unique states of consciousness, while other researchers believe relaxation practices able to produce the same kind of state made by
Chapter 4 discusses the several states of consciousness: the nature of consciousness, sleep and dreams, psychoactive drugs, hypnosis, and meditation. Consciousness is a crucial part of human experience, it represents that private inner mind where we think, feel, plan, wish, pray, omagine, and quietly relive experiences. William James described the mind as a stream of consciousness, a continuous flow of changing sensations, images thoughts, and feelings. Consciousness has two major parts: awareness and arousal. Awareness includes the awareness of the self and thoughts about one's experiences. Arousal is the physiological state of being engaged with the environment. Theory of mind refers to individuals understanding that they and others think,
My ideas resemble a mixture of Rosalind Cartwright and Sigmund Freud’s theories on dreams. Freud believed that the purpose of our dreams is to attain a
I will commence by defining what makes a mental state conscious. This will be done aiming to distinguish what type of state we are addressing when we speak of a mental phenomenon and how is it, that can have a plausible explanation. By taking this first approach, we are able to build a base for our main argument to be clear enough and so that we can remain committed to.
McGinn begins by rejecting both traditional materialism and dualism. Materialists propose that the brain and consciousness are one and the same: thus, brain waves not only correlate with consciousness, they are consciousness. McGinn faults this position for ignoring the very nature of co...

It is universally known that dreams are full of meanings and emotions. In Freud’s theory, all dreams are wish fulfillments or at least attempts at wish fulfillment. The dreams are usually presented in an unrecognizable form because the wishes are repressed. Freud proposes there are two levels in the structure of dreams, the manifest contents and the latent dream-thoughts. The manifest dream, a dream with understandable contents, is a substitute-formation that hides latent dream-thoughts, which are the abstract ideas in dreams. This translation of latent dream-thoughts to the manifest dream-content is defined by Freud as “dream-work”. Dream-work consists of certain types of transformation.
Dreams have been thought to contain significant messages throughout many cultures. A dream is an unfolding sequence of perceptions, thoughts, and emotions that is experienced as a series of real-life events during sleep. The definitions of dreams are different among studies, which can also lead to quite different results. Perhaps, the dream interpretation has becoming increasingly popular. In this paper, I will talk about what I have learned about three different views of dream interpretations. One theory made by Sigmund Freud who believed that dreams are triggered by unacceptable repressed wishes, often of a sexual nature. He argued that because dreams we experience are merely disguised versions of people real dreams. The other theory called activation–synthesis theory, made by Allan Hobson and Robert McCarley, based on the observation that during REM sleep, many brain-stem circuits become active and bombard the cerebral cortex with neural signals. The last theory, proposed by William Domhoff, is called the neurocognitive theory of dreaming, which demonstrates that dream content in general is continuous with waking conceptions and emotional preoccupations. Thus, dreaming is best understood as a developmental cognitive achievement that depends upon the maintenance of a specific network of forebrain structures. While each theory has different belief system and approach method, it is a great opportunity to know how former psychologists contributed to the field of dream interpretation.
Psychology, neuroscience try to explain them, 2012). He studied dreams to better understand aspects of personality as they relate to pathology. Freud believed that every action is motivated by the unconscious at a certain level. In order to be successful in a civilized society, the urges and desires of the unconscious mind must be repressed. Freud believed that dreams are manifestations of urges and desires that are suppressed in the unconscious. Freud categorized the mind into three parts: the id, the ego, and the superego. When one is awake, the impulses if the id are suppressed by the superego, but during dreams, one may get a glimpse into the unconscious mind, or the id. The unconscious has the opportunity to express hidden desires of the id during dreaming. Freud believed that the id can be so disturbing at times that the id’s content can be translated into a more acceptable form. This censor leads to a sometimes confusing and strange dream image. According to Freud, the reason one may struggle to remember a dream is because the superego protects the conscious mind from the disturbance of the unconscious mind (Dream Theories,
During Freud’s time, society typically viewed dreams as an intervention of a higher being or entity (Freud, 1900, p.4). However, Freud made the claim that dreams are the product of the dreamer and also that it serves two purposes. First, dreams form to keep a person asleep at night by blocking out external stimuli, much in the same way a person consciously does when turning off the light and minimizing noise before going to bed (“Freud’s Approach,” 2000). Next, Freud (1900) viewed humans as having grotesque sexual urges that “are suppressed before they are perceived” (p.37) in order to protect the person and allow him or her to get along in society; however, dreams serve the purpose of releasing these repressed desires as wishes which are disguised in the dream. Because a person cannot readily be aware of the unconscious wish, the dream is divided into two ...

What is a dream? Why do we have dreams? Do dreams have deeper meaning in our lives? The answers to these questions have eluded and intrigued many psychologists throughout history and have sparked my interest as well. As an avid and vivid dreamer I have often found myself wondering what the true meanings to my dreams were. So what are dreams? “Strictly speaking, dreams are images and imagery, thoughts, sounds and voices, and subjective sensations experienced when we sleep.”1 Even after thousands of years of research, psychologists have still not come to an agreed answer on why we dream. There are as many opinions out there as there are individual dreams. Some psychologists believe dreaming is simply the minds way of distracting itself from outside information during sleep to allow people to get deep rest. Others such as Dr. Eric Hartman suggest dreams serve almost as a psychotherapy in which the brain can make connections between different emotions and thoughts in a safe protected environment. Do dreams have any direct correlation to everyday events and experiences? Are they meant to aid individuals in understanding and interpreting their world around them?
“Consciousness is defined as everything of which we are aware at any given time - our thoughts, feelings, sensations, and perceptions of the external environment. Physiological researchers have returned to the study of consciousness, in examining physiological rhythms, sleep, and altered states of consciousness (changes in awareness produced by sleep, meditation, hypnosis, and drugs)” (Wood, 2011, 169). There are five levels of consciousness; Conscious (sensing, perceiving, and choosing), Preconscious (memories that we can access), Unconscious ( memories that we can not access), Non-conscious ( bodily functions without sensation), and Subconscious ( “inner child,” self image formed in early childhood).
During prescientific days, dreams were interpreted as ‘manifestations’ of a ‘higher power’. Since the introduction of psychology, dreams have had 4 distinct interpretations. The first interprets dreams as a “liberation of the spirit from the pressure of external nature”. The second interprets dreams as “accidental disturbances from ‘internal organs’. The third interprets dreams as a foretelling of the future. The last interpretation is Freud’s. He interprets dream as an expression of subconscious desires.
