Inspired by techniques to train deep neural networks, researchers have proposed a new hypothesis of dreaming. The hypothesis suggests the strangeness of our dreams may help our brains better generalize our day-to-day experiences.
More than 80% of patients nearing the end of life reported experiencing dreams that were vivid, meaningful, and transformative. Patients reported the dreams made them feel supported, reassured and helped them to accept their impending death.
35% of patients who used ketamine to manage pain reported significant side effects ranging from hallucination, out-of-body experiences, visual disturbances, and urinary dysfunction. 20% of the side effects were linked directly to ketamine, and 15% associated with ketamine in combination with other drugs.
A new study reports relapse dreams are more common in those with severe clinical histories of addiction. Researchers say the frequency of these relapse dreams decrease as the brain and body adapt to abstinence.
According to a new study, the consequence of daily stress is linked to an increase in REM sleep. Researchers report the increase is associated with genes involved in apoptosis and cell survival. The findings shed light on how stress leads to mood disorders, and how changes in sleep contribute to this.
