Dreaming has fascinated and mystified humankind for ages: the bizarre and evanescent qualities of dreams have invited boundless speculation about their origin, meaning and purpose. For most of the twentieth century, scientific dream theories were mainly psychological.

REM sleep and dreaming: towards a theory of protoconsciousness and quality during the sleep–wake...

John Allan Hobson born June 3, is an American psychiatrist and dream researcher. He is known for his research on rapid eye movement sleep. Hobson grew up in Hartford, Connecticut. He worked in numerous hospitals and research laboratories over the years and became the Director of the Laboratory of Neurophysiology at the Massachusetts Mental Health Center. Hobson has received four awards for his work: [1]. Hobson's research specialty is quantifying mental events and correlating them with quantified brain events, with special reference to waking, sleeping and dreaming.

Dream Consciousness pp Cite as. The role of sleep and dreaming in maintaining emotional stability represents a very tangible and practical example of protoconsciousness as a mental state that supports the proper functioning of normal waking consciousness. Normal sleep has been shown to promote basic mammalian mechanisms of emotion regulation such as habituation, extinction and physiological homeostasis Pace-Schott et al. Sleep deprivation experiments suggest that sleep is also essential to cognitively based emotion regulatory functions such as accurate identification of facial emotion van der Helm et al. Dreaming has been widely hypothesized to take part in this emotion regulatory process. For example, Rosalind Cartwright has suggested that negative affect is progressively ameliorated across dreams elicited from successive REM periods of a night in mildly depressed college students Cartwright et al. Similarly, she has linked a pattern of progression from negative early dreams to positive late dreams across the night with remission at 1 year in persons meeting Beck Depression Inventory criteria for depression Cartwright et al.

Primary consciousness can be defined as simple aware-ness that includes perception and emotion. As such, it is ascribed to most mammals. By contrast, secondary consciousness depends on language and includes such features as self-reflective awareness, abstract thinking, volition and metacognition1. In adult humans, dreams that occur during rapid eye movement REM sleep have features of primary consciousness but, as shown in FIG. In humans, consciousness varies dramatically in intensity and quality during the sleepwake cycle. Whether we are awake and alert with the full panoply of secondary aspects of consciousness , asleep with greatly diminished awareness or dreaming with the internally generated perceptions and emotions of pri-mary consciousness depends on the three objectively identifiable states of the brain: waking, non-rapid eye move-ment NREM sleep and REM sleep BOX 1. The strategies by which those states are investigated are outlined in Supplementary information S2 box.

I suggest that brain activation in sleep allows the development and maintenance of circuits necessary for higher brain functions, including consciousness. Brain activation and sleep occurs early in the development of mammals and birds.

Known for his AIM model of dreaming states and his extensive work on sleep, Allan Hobson is both an experimental researcher and a psychiatrist, and is Professor Emeritus at Harvard Medical School. He began having lucid dreams after reading about them in , and for decades he kept a dream journal. His dreams stopped after a stroke in but began again thirty-six days later, just as he began to walk again. He has long tried to understand the function of sleep, recently proposing that the brain optimises itself during sleep by minimising free energy and reducing the complexity of its model of the world. He has a dairy farm in Vermont where he has restored old buildings to house exhibitions and an art gallery.

The science of dreaming constitutes a relevant topic in modern-day neuroscientific research and provides major insights into the study of human consciousness. Linking specific, universal, and regularly occurring stages of sleep with dreaming encourages the direct and systematic investigation of a topic that has fascinated humankind for centuries. In this review, we explore to what extent individuals dream during periods of rapid eye movement and non-rapid eye movement sleep, and we introduce research on lucid dreaming.
