Core Viewpoint - The 34th World Mental Health Day emphasizes the importance of accessible mental health services for everyone, highlighted by the 11th Vocational Skills Competition for Mental Rehabilitation in Beijing [1] Group 1: Event Overview - The competition is co-hosted by the Beijing Municipal Health Commission and the Beijing Disabled Persons' Federation, with participation from 23 teams and nearly 200 mental rehabilitation participants and staff from various mental health institutions across 16 districts in Beijing [1] - Five competition categories were established to enhance participants' practical skills, cognitive functions, emotional management, teamwork, and daily decision-making abilities [1] Group 2: Mental Health Statistics - Over 100 million people in China suffer from various mental disorders, with mental rehabilitation being a crucial method alongside medication to prevent relapse and improve patients' independence and social adaptability [1] - The current prevalence rate of mental disorders in China is reported at 17.5%, encompassing severe mental disorders as well as milder conditions like depression, anxiety, and substance dependencies [2] Group 3: Contributing Factors to Mental Disorders - The increase in mental disorder prevalence is attributed to both biological factors, such as brain structure abnormalities and genetic influences, and environmental factors, including academic, work, interpersonal, and economic pressures [2] - Individual personality traits and coping mechanisms also play a significant role in the risk of developing mental health issues [2]

Group 1 - The exploration of dreams has evolved from ancient beliefs to modern neuroscience, indicating that dreams may have significant connections to human thought, memory, and creativity [1][3][17] - REM sleep, discovered in 1953, is characterized by high brain activity similar to wakefulness, where most vivid dreams occur [3][4][6] - Dreams are not random; they are closely linked to daily experiences, emotions, and memories, facilitated by the brain's complex neural networks, particularly the Default Mode Network (DMN) [11][12][13] Group 2 - During REM sleep, the brain processes and reorganizes memories, often amplifying emotional experiences, which explains the intense feelings associated with dreams [12][13] - The brain's activity during REM sleep involves various regions, such as the visual cortex for imagery and the limbic system for emotions, while the prefrontal cortex's activity is suppressed, leading to illogical dream narratives [9][10][11] - Dreams may serve as a means of emotional regulation, helping individuals cope with stress and anxiety by reprocessing emotional memories [12][13] Group 3 - The similarities between dreams and hallucinations suggest a shared neurobiological basis, particularly in conditions like schizophrenia, where individuals may struggle to distinguish between reality and their internal perceptions [14][15] - Lucid dreaming, where individuals maintain self-awareness, may offer therapeutic potential for those experiencing hallucinations, allowing them to better control their experiences [16] - The ongoing research into dreams not only seeks to unravel their mysteries but also aims to address fundamental questions about consciousness and reality [17]
