Dreams Reflect Multiple Memories and Anticipate Future Events

53% of dreams can be traced to memories, and of those, 50% are linked to memory sources of multiple previous life events. Additionally, 26% of dreams are associated with impending events. Future-orientated dreams become more prevalent during deeper stages of sleep.

Our Dreams’ Weirdness Might Be Why We Have Them

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.

Real-Time Dialogue With a Dreaming Person Is Possible

During REM sleep, people are able to interact with researchers and engage in real-time communication. The study reports while dreaming, people can follow instructions, perform simple math, answer yes and no questions, and tell the difference between different sensory stimuli.

Being ‘mind-blind’ may make remembering, dreaming and imagining harder

Aphantasia, a disorder in which people are lack the ability to mentally visualize imagery, is also associated with a widespread pattern of changes to other important cognitive processes. Many with aphantasia report a reduced ability to recall past events, imagine the future, and dream.

The dreaming brain tunes out the outside world

The brain tunes out information from the outside world, such as the sound of speech, during REM sleep. During light sleep, the brain prioritizes meaningful speech, just as it does during a wakeful state. Researchers believe the mechanism enables the brain to protect the dreaming phase, which is essential for memory consolidation.

Ayahuasca DMT compound changes brainwaves to vivid ‘waking-dream’ state

DMT alters electrical activity in the brain. The compound significantly decreases alpha wave activity, the dominant rhythm associated with wakefulness, and increases theta waves, associated with dreaming. Overall brain activity becomes more chaotic and less predictable. The findings advance the understanding of the neurobiological underpinnings of immersive states of consciousness.

Finding the root of consciousness: Is this brain cell your ‘mind’s eye’?

Researchers believe they have identified specific neurons that are responsible for conscious awareness. Previous studies have implicated both thalamocortical circuits and cortico-cortico circuits in consciousness. The new study reports these networks intersect via L5p neurons. Directly activating L5p neurons made mice react to weaker sensory stimuli. The researchers say if consciousness requires L5p neurons, all brain activity without them must be unconscious.
