He considers the prospective function to have two meanings: it is both integrative and synthetic (or "reductive"). [H 2] Within this prospective function, Jung includes a category of dreams: those in which certain psychic events penetrate the unconscious sphere. This is the case of dreams announcing the death of a loved one.
Dreaming is a state of the brain that is similar to yet different from the waking consciousness, and interaction and correlation between the two is necessary for optimal performance from both. One study conducted measuring brain activity via EEG used Hobson's AIM model to show that quantitatively dream consciousness is remarkably similar to ...
Dreams and reports of dreams are produced in distinct states of consciousness resulting in a delay between the dream event and its recall while awake. During this time lag forgetting may occur resulting in an incomplete report. Forgetting is proportional to the amount of time elapsed between the experience and its recall. [2]
Work in oneirology overlaps with neurology and can vary from quantifying dreams to analyzing brain waves during dreaming, to studying the effects of drugs and neurotransmitters on sleeping or dreaming. Though debate continues about the purpose and origins of dreams, there could be great gains from studying dreams as a function of brain activity.
Dreams can usually be recalled if a person is awakened while dreaming. [98] Women tend to have more frequent dream recall than men. [98] Dreams that are difficult to recall may be characterized by relatively little affect, and factors such as salience, arousal, and interference play a role in dream recall. Often, a dream may be recalled upon ...
Two other neurotransmitters, orexin and gamma-Aminobutyric acid (GABA), seem to promote wakefulness, diminish during deep sleep, and inhibit paradoxical sleep. [ 3 ] [ 26 ] Unlike the abrupt transitions in electrical patterns, the chemical changes in the brain show continuous periodic oscillation.

This is when most dreaming occurs. Overall, REM sleep usually accounts for up to two hours of sleep time and most people can remember their dreams only if woken directly from REM sleep. [3] It is known from laboratory studies of brain waves that, just before entering REM sleep and while in it, powerful electrical signals pass through the brain.
