Is disagreement about consciousness largely owed to no adequate initial clarification of the subject, to people in fact answering different questions clarified as actual consciousness. Philosophical method like the scientific method includes transition from the figurative to literal theory or analysis. A new theory will also satisfy various criteria not satisfied by many existing theories. The objective physical world has specifiable general characteristics including spatiality, lawfulness, being in science, connections with perception, and so on. Actualism, the literal theory or analysis (...) of actual consciousness, deriving mainly from the figurative database, is that actual consciousness has counterpart but partly different general characteristics. Actual consciousness is thus subjectively physical. So physicality in general consists in objective and also subjective physicality. Consciousness in the case of perception is only the dependent existence of a subjective external physical world out there, often a room. But cognitive and affective consciousness, various kinds of thinking and wanting, differently subjectively physical, is internal – subjectively physical representations-with-attitude, representations that also are actual. They differ from the representations that are lines of type, sounds etc. by being actual. Thus they involve a subjectivity or individuality that is a lawful unity. Actualism, both an externalism and an internalism, does not impose on consciousness a flat uniformuity, and it uniquely satisfies the various criteria for an adequate theory, including naturalism. Actual consciousness is a right subject and is a necessary part of any inquiry whatever into consciousness. All of it is a subject for more science, a workplace. There is no unique barrier or impediment whatever to science, as often said, no want of understanding of the mind-consciousness connection, no known unique hard problem of consciousness, no insuperable difficulty having to do with physicality and the history of science, no arguable ground at all of mysterianism.

Sleep and dreaming are important daily phenomena that are receiving growing attention from both the scientific and the philosophical communities. The increasingly popular predictive brain framework within cognitive science aims to give a full account of all aspects of cognition. The aim of this paper is to critically assess the theoretical advantages of Predictive Processing (PP, as proposed by Clark 2013, Clark 2016; and Hohwy 2013) in defining sleep and dreaming. After a brief introduction, we overview the state of the (...) art at the intersection between dream research and PP (with particular reference to Hobson and Friston 2012; Hobson et al. 2014). In the following sections we focus on two theoretically promising aspects of the research program. First, we consider the explanations of phenomenal consciousness during sleep (i.e. dreaming) and how it arises from the neural work of the brain. PP provides a good picture of the peculiarity of dreaming but it can’t fully address the problem of how consciousness comes to be in the first place. We propose that Integrated Information Theory (IIT) (Oizumi et al. 2014; Tononi et al. 2016) is a good candidate for this role and we will show its advantages and points of contact with PP. After introducing IIT, we deal with the evolutionary function of sleeping and dreaming. We illustrate that PP fits with contemporary researches on the important adaptive function of sleep and we discuss why IIT can account for sleep mentation (i.e. dreaming) in evolutionary terms (Albantakis et al. 2014). In the final section, we discuss two future avenues for dream research that can fruitfully adopt the perspective offered by PP: (a) the role of bodily predictions in the constitution of the sleeping brain activity and the dreaming experience, and (b) the precise role of the difference stages of sleep (REM (Rapid eye movement), NREM (Non-rapid eye movement) in the constitution and refinement of the predictive machinery.
