Modern Dream Theory The most recent theory of dreaming is that it is used to solve problems. If we are having challenges at work or in a relationship, our dreams may examine these issues while we sleep and may even provide us with a solution. When individuals say they’re going to “sleep on” an issue, they’re implying that they’re hoping for a solution while they’re sleeping. Why do humans dream? The “problem-solving theory” seems to be pretty credible.  Jacky Smith

the restorative theory refers to the body and how it allows individuals to repair and replete cellular components that are needed for the biological functions that people use throughout the time they are awake. This theory is sourced from findings that many functions in the body like muscle, tissue and other growth release important hormones for biological growth especially when asleep. overall this theory believes that sleep is used to repair the body and the brain. Rachel and Stephen Kaplan came up with this theory in the 1980s when writing their book.

memory consolidation dream theory suggests that dreaming is influenced by the consolidation of memory during the time people sleep. this theory refers to the process of temporary and labile memory that is transferred into more stable and long lasting forms. memory consolidation was first approached in 1990 by Muller and Plizecher. overall this theory claims that sleep itself is very important in learning new information.

Energy Conservation Theory

Some believe that the main purpose of sleep is to conserve energy and that by sleeping we are able to function at a low metabolism which lowers the calories we need to eat. It was also harder to hunt for food at night so it was better to stay hidden.
This theory was created by Allen Rechtschaffen

·        Claims that NREM sleep restores biological processes that have deteriorate during the day and that REM sleep replenishes and renews brain processes through the process of protein synthesis.

Creativity Dream Theory (James Newlands)

Dreamt up by Otto Loewi, he looked into what he hypothesised the night before: Nerve cells communicate by exchanging chemicals, or neurotransmitters. The confirmation of that idea earned him a Nobel Prize in medicine in 1936.

Penny Lewis expanded on this theory to explain how creativity and dreams are linked. During the later stages of sleep, the brain begins to replay memories (random memories from points of the persons life) these replaying memories help the brain to integrate this revision into new memories (resulting in dreams).

Brian plasticity theory is the theory that sleep is essential for neural reorganisation and for the growth of the brains daily functions and structure. The theory says that sleep plays a huge role in the development of infants and children and this is why they need upwards of 14 hours of sleep a day. It was developed in the nineteenth century by William James and was first talked about in his book The Principles of Psychology in 1890.

This is one of the earliest theories of sleep and is sometimes called the adaptive or evolutionary theory. This theory suggests that our inactivity at night is an adaption of survival insitincts by keeping us safe and inactive at night, when predators are most likely to attack. Through natural selection this process then became recognized as sleep. - cant find any information on who created this theory :) - April
