( 9) hypothesized that the ability to dream and remember dreams is associated with the development of cognitive processes (perception, learning, language, thinking, attention, memory, motivation and emotion). Analyzing the ability to sleep and dream in the fetal period, childhood, adulthood and old age, Mangiaruga et al. Analyzing DRF through the compilation of a clinical diary, Armitage ( 8) noted that in males DRF decreased during stress periods, while for females it was the opposite. Schredl & Montasser ( 6, 7) thought instead that DRF depended on personality, visual memory capacity, creativity, the frequency of nocturnal awakenings and attitude towards dreams. ( 1), dream recallers had better memory towards visual stimuli compared to non-recallers. Schonbar ( 5) hypothesized that DRF could be influenced by the individual’s lifestyle, distinguishing an “inner accepting” lifestyle with high DRF, less curiosity in non-interpersonal problems and a high feeling of control over one’s own life, from an “inner refusing” lifestyle with low DRF and opposite characteristics.
