We analyzed the dream locations in 680 dream reports longer than 20 words recorded over a calendar year in a single geographer subject, and compared them with the exhaustive, concomitant daytime log of the 122 cities he visited during the same year. Among the dream reports, 24.4% (from 38% of the nights) named the geographic location in dreams. There were 107 cities visited in dreams and 122 visited during daytime: only 30 locations were common to dream and daytime life. Dream reports were longer when they indicated a location (90 ± 92 vs. 70 ± 67 words/dream, p = 0.008). In contrast, 72% (77/107) of locations visited in dreams had not been visited during the same year and 20 (18.7%) dreamt locations had never been visited during the entire life. In the 139 nights including a dreamt location, there was a timely (same night) concordance of 32.5% between the location visited the day before and the location in dream. Another 13.5% dreamt locations corresponded to locations visited within 10 days prior to target nights (without any peak at the 7<sup>th</sup> day), whereas 11.5% dreamt locations were locations to be visited the next day(s) (anticipation effect). This within-subject, large single longitudinal dream series, concomitant with an exhaustive log of visited geographic locations, confirms the continuity hypothesis for incorporation of recently visited locations in dreams, does not confirm the 7<sup>th</sup> day delay in incorporating location sources, and shows a small but interesting anticipation effect in dreams of future visited locations.</p> ER -
