The Ephemeral Nature of Dreams

The article, Why Do We Forget So Many of Our Dreams? - Scientific American, delves into the intriguing phenomenon of why we forget most of our dreams. The primary stage of dreaming, REM (Rapid Eye Movement) sleep, is where the brain's activity mirrors that of a waking state. However, the regions responsible for transferring memories to long-term storage are less active during this phase. This means that its memory fades away unless we awaken immediately after a dream. The duration of REM sleep increases throughout the night, making the last dream before waking the most memorable. Factors like age, gender, and personality traits also influence dream recall. Interestingly, focusing on dreams or even reading about them can enhance our ability to remember them.
