An overview of theories on why we dream and the narrative content of dreamtime.
This paper discusses how all individuals do dream on a nightly basis, how sleeping is a necessity and dreaming is inevitable and unavoidable. It examines Sigmund Freud’s theory that certain life experiences, traumatic memories and taboo desires are sufficiently threatening that special mental processes permanently banish them from the active, daily waking consciousness. It also looks at other, more biologically based explanations, for why human beings dream including lucid dreaming and hallucinations.
Biologically speaking, for instance, insomnia can often produce hallucinations, after an individual has been subject to too much stimulation, either of a chemical or environmentally induced kind. Jet lag and shift work can stimulate a disruption of the body’s natural circadian rhythms one’s natural arousal levels, metabolism, heart rate, body temperature, and hormonal activities as they respond to light and dark and other external pressures and life patterns-that disrupt the ebb and flow or the ‘ticking’ of the dreamer’s internal clock and disrupt a comfortable sense of consciousness during dreamtime, thus producing unpleasant dreams such as the ‘underwear’ exposure dream delineated above.
