The major breakthrough in the study of dreams came in 1953 when researchers Eugene Aserinsky and Nathaniel Kleitman studied and discovered what happens when a person falls asleep.They found that the body enters into a psycho-physiological state in intervals of 90 minute cycles during sleep. This physiological state consists of heightened brain activity, Rapid Eye Movement (REM), increased breathing, a temporary paralysis of the body and genital engorgement. Through experiments, they confirmed that these physiological observations were the result of the person being in the dream state.

The independent variable is the temperature.
The study aims to assess how the temperature level affects another variable, that, in turn, will be the dependent variable: the mood of the participants. The aim of the study is to conclude whether it is possible or not to infer causality between those two, in other words, to see whether different levels of temperature (<em>the cause</em>), trigger the emergence of a certain type of mood <em>(the effect).</em>
