In 1977 there was a study done about sleep positions relating to personality traits. There were main points within the study that strongly urged that sleep positions reflected a person's personality. In contrast, a personality study conducted in the year 2012, suggested that the position a person sleeps in is related to specific traits of their personality. Their study consisted of 332 participants that were psychology majors. The results found did not match what was previously concluded. There were no strong points leading to prove that there was such a relation, and in fact, the results were found to be quite weak between the association.
