The author, MSU Psychology Professor Michael R. Nadorff, aims to provide empirically-supported treatments for this debilitating disorder.
A large-scale study published in JNeurosci reveals distinct brain activity patterns during lucid dreaming compared to rapid eye movement sleep and wakefulness. The findings suggest shifts in brain region activation and communication that may be linked to changes in perception, memory processing, self-awareness, and cognitive control.
Researchers are using smartphones to capture naturalistic data on memory, sleep, and dreams, finding that a single night of sleep influences memory for the events that occurred the day before. Memories following sleep were more vivid, felt temporally closer, and were easier to recall.
A study of 733 older female participants found that those with increasing sleepiness had double the risk of stable sleepers. Poor sleep quality in midlife and delayed dream phase are also linked to a higher risk of dementia. The study adds to recent research on the relationship between sleep patterns and dementia.

A new theory of dreaming proposes that our brains create strange dreamscapes to counteract overfitting by familiarizing themselves with everyday experiences. This 'overfitted brain hypothesis,' inspired by AI regularization techniques, suggests dreams serve a purpose in generalization and world understanding.
Researchers found that octopuses alternate between an 'active sleep' stage and a 'quiet sleep' stage, characterized by dynamic color changes and muscular twitches. The findings suggest that octopuses may experience something akin to dreams during the 'active sleep' state.

A new study from UNSW Sydney found that people with aphantasia, a lack of mental visual imagery, experience changes in other cognitive functions. They reported reduced ability to remember past events, have less vivid dreams and struggle with imagination. The research highlights the complexity of aphantasia and its impact on daily life.
Researchers found that the brain filters out external sounds during REM sleep, prioritizing meaningful speech during light sleep. This mechanism enables the brain to protect the dreaming phase, necessary for emotional balance and learning consolidation.
Bern researchers have identified the neurons responsible for rapid eye movements (REM) during sleep, a characteristic of paradoxical sleep with high dream activity. The discovery was made by a team of scientists who found that activation of these neurons causes rapid eye movement and can be used to study the function of this phenomenon.
