In what disorder does one typically have poor recall of dream imagery?

The disorder characterized by poor recall of dream imagery is Non-Rapid Eye Movement (NREM) Sleep Arousal Disorder. This condition occurs during sleep stages, typically in phases 3 and 4 of NREM sleep, where the individual might experience episodes of incomplete awakening, such as sleepwalking or sleep terrors, without having any vivid dreams to recall. The lack of vivid dream recall is integral to this disorder because these arousals take place during deep sleep when dreams are not typically being formed.

In contrast, other disorders like Nightmare Disorder are associated with vivid and distressing memories of dreams, prompting individuals to have clear recollections of their nighttime experiences. Restless Leg Syndrome and Obstructive Sleep Apnea relate to physical and respiratory disturbances during sleep rather than cognitive recall of dreams. Therefore, the nature of NREM Sleep Arousal Disorder aligns with the symptoms described—poor recall of dream imagery due to the timing and type of sleep disturbances that occur.
