His interest in dreams began when he started collecting reports of dreams that were written by his students (anonymously, of course). He then continued to collect reports from others, and when he passed away he had acquired over 50,000 dream reports. Interestingly, Hall found that dream reports from different individuals were more alike than they were different, and this demographic included children, adults, and people who were spread across the entire world. The main differences present in dreams were consistent with the differences that those people experienced in their conscious life as well (such as cultural factors). From this, he proposed that there is a “continuity” between a persons wakefulness and their dream experiences (Hall, 1966).
