Dreams have a foresight function, enabling us to find a way out of an immediate conflict. [I 2] To reduce the polysemy of the term, Jung sometimes speaks of the "intuitive function" of dreams. [G 3] This prospective function is not in fact a premonitory dream, but teaches the dreamer a path to follow. [2]
A dream has all features of primary consciousness but is produced in the brain without external stimulation. Unlike the waking state, the brain cannot recognize its own condition; that it is in the midst of the dream and is not the same as the real world. [1]
One significant shortcoming of dream studies is the necessary reliance on verbal reports. The dream event is reduced to a verbal report which is only an account of the subject's memory of the dream, not the subject's experience of the dream itself. These verbal reports are also at risk of being influenced by a number of factors.
One aspect of dreaming studied is the capability to externally influence the contents of dreams with various stimuli. One such successful connection was made to the olfactory system, influencing the emotions of dreams through a smell stimulus. Their research has shown that the introduction of a positive smelling stimulus (roses) induced ...
Most modern dream study focuses on the neurophysiology of dreams and on proposing and testing hypotheses regarding dream function. It is not known where in the brain dreams originate, if there is a single origin for dreams or if multiple regions of the brain are involved, or what the purpose of dreaming is for the body or mind.
Reverse learning is a neurobiological theory of dreams. [1] In 1983, in a paper [2] published in the science journal Nature, Crick and Mitchison's reverse learning model likened the process of dreaming to a computer in that it was "off-line" during dreaming or the REM phase of sleep.
Interobjects differ from typical dream condensations in which two objects are fused into one. Instead, the condensation is incomplete. Some examples from the literature on dreams include "a piece of hardware, something like the lock of a door or perhaps a pair of paint-frozen hinges" [ 1 ] and "something between a record player and a balance ...
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
