Introduction
People have varied natures of dreams. Because of this, the researcher intends to find out what factors influence these particular types of dreams. She also aims to determine the valid dream categories and the common distinct factors that may be causing these.
Since dreaming is a broad subject matter, the study will look into a number of other related themes and issues as well. The research will further probe into Hobson and McCarley’s (1977) Activation Synthesis Hypothesis. Moreover, the research will also tackle Freud’s concept of wish fulfillment in his psychoanalytic theory and posthypnotic dream suggestion as stated in Atkinson, Atkinson, Smith and Bem’s (1990) Introduction to Psychology. Also, it will delve into the Cognitive Theory of Dreaming. In addition, the research will also include a lot of other studies and articles associated with factors that affect dreaming and dream interpretation as well.
Body
According to Kosslyn and Rosenberg (2001) in their article, “What triggers Particular Dreams?” certain types of dreams seem to be related to previous episodes that occurred in the day. It is stated there that a dream often echoes a short term lack in a particular stimuli. One instance acknowledged in the book was that of water deprived people for the day dreaming of drinking in their sleep.
The Posthypnotic pre-dream suggestion (Atkinson, Atkinson, Smith & Bem, 1990) is another possible way that could have an influence on the dream’s content. A study was made using these methods and in the results it showed that some dreams reflected other aspects of the suggestion without the specific elements while others reflected on the suggestion itself.
In reference to one of Baron’s (1992) articles in Psychology: Second edition, it is possible that external events are incorporated into a person’s dream. In an experiment, Dement and Wolpert, (1958) sprayed water on participants in REM sleep. And in majority of the instances, participants accounted that there was water in their dreams.
In chapter 8 of Domhoff’s (1996) Finding Meaning in Dreams: A Quantitative Approach, it proposes that there is a relationship between our thoughts and behaviours while we are awake and the categories and contents of our dreams. The chapter implies that the concerns people express in their dreams are the concerns they have during the time they are conscious and awake; their dreams correspond to what they think about or do in their waking life.
Raija-Leena Punamaki (1998) conducted a study for the Journal of Cross-Cultural Psychology; she tried to determine the impact of culture, a violent environment, gender, and age in dream content. Her study was conducted on 205 children in three groups: 80 Palestinians living in a violent environment and 45 Palestinians and 80 Finnish people living in peaceful areas. The findings confirmed that living in a violent environment affected dream content more than personal and culture factors.
According to Schone, Sok, Myers and Hollinger (2001) in their recent study “Factors That Influence Dreams” they also attempted to determine factors that affected people’s dreams. From their findings they were able to conclude that gender is a factor that affects a person’s dream. In their results, women had more dreams regarding sex and violence while men had more dreams regarding examinations. However, their findings also indicate that there are no particular correlations between people having similar courses and similar dreams. Thus, this implies that courses may not be a factor that would affect the nature a person’s dream. Lastly, they were able to prove that their hypothesis regarding the correlation between where one lives and one’s dreams was correct. Based on the resulted graphs of their study, people living in each dorm did have dreams independent of people of the other dorms. However, despite all this, according to them, their study turned out to be subjective in a lot of ways which is why it may still not be considered to be completely valid.
In Hartmann and Basile’s (2003) journal study “Dream Imagery Becomes More Intense after 9/11/01” their results indicate that traumatic events like the attacks of 9/11/01, for instance have a detectable effect on dreams. According to the study, it particularly increases dream image intensity. Also, these findings are consistent with previous ones that dream image intensity rather than dream length and content can be considered a measure of emotional arousal.
In reference to Delorme, Lortie-Lussier, De Koninck’s journal study Stress and Coping in the Waking and Dreaming States During an Examination Period, they found out that incorporation dreams did not reveal more stress, negative emotions and more coping strategies indices than dreams without incorporation. But a significant negative relationship was discovered between emotions of harm and threat in waking and negative emotions in dream content.
According to Ullman’s (1973) article Societal Factors in Dreaming; all elements in dreams have social referents. They may have their source in the tools, symbols, and even events of social living. Furthermore an element also has a social or objective meaning which corresponds with the needs of the dreamer and makes it available to the dreamer in his sleep.
In Hobson and McCarley’s (1977) Activation Synthesis Hypothesis, it states that that dreams are a mere accidental incident caused by firing of neurons in the brain. The body's motor system then receives these random fired signals, but due to the paralysis that occurs during REM sleep, the brain is faced with a paradox. And the dream is its form of attempting to explain or make sense of what has occurred.
Freud (1900, 1953) believed that the reason we dream is because of wish fulfilment which is an unconscious attempt to fulfil needs (especially sex and aggression) that cannot be expressed or that are not satisfied while awake. However, the Cognitive Theory of Dreaming as stated in Santrock’s (2003) Psychology suggests that there is no real symbolic content in dreams unlike what Freud claimed. Dreaming only entails problem solving, memory and information processing.
Conclusion
Based on all these findings, the researcher can infer that there is truth that environmental factors play a big role in the influence of people’s dreams. As stated by Kosslyn and Rosenberg (2001) certain types of dreams seem to be triggered by episodes in the day where in there is a short term lack of a certain stimuli. In addition, dreams may also be influenced through the posthypnotic pre dream suggestion (Atkinson, Atkinson, Smith & Bem, 1990). Baron (1992) also claimed that external events like spraying water on the participants in one of the experiments may be incorporated into dreams.
A violent environment more than gender and culture had a greater impact on dream content according to Raija-Leena Punamaki (1998). A dangerous and brutal environment was associated with vivid dreams of persecution and aggression. Moreover, the main results from Schone, Sok, Myers and Hollinger’s (2001) study indicate that difference in living areas and gender affect the variance of people’s dreams. Finally, based on Hartmann and Basile’s (2003) journal study, results show that traumatic events also do have a measurable effect on dream image intensity.
