Abstract
When people wake up from a long night sleep, dreams are memorized, sometimes forgotten. What are the factors that influences the clarity and quality of dream recalls when people wake up? Data were collected from the author himself using EEG, survey and introspection. Totally 7 nights of data were collected for this investigation. The results demonstrated borderline negative correlation among the level of clarity of dream recall and the time interval between last REM and wake up. Results showed that the closer one woke up from REM sleep, the clearer the dream was recalled. Further improvement can be made on the variety of participant chosen and other possible factors that influence the clarity of dream recall.
