Unfortunately, there are very few studies which have thoroughly investigated psychotic episodes, and the ability to predict this disorder remains unclear. (Schimmelmann, B., Walger, P., & Schultze-Lutter, F., 2013). Reviewing the previous conditions for accidental and pathological causes, we can come to understand that all of these accidental or pathological causes share the component of reduced self-awareness. Therefore, ASCs cannot only be caused naturally but they can be induced intentionally with methods including hypnosis meditation, amongst others. There are also ASCs which are caused by less recreational purposes; people who utilize illegal substances, or heavy dosages of medications, as well as large amounts of alcohol, can indeed comply with the definition of an ASC (Revonsuo et al., 2008). Neurobiological models of altered state experiences Entropic brain hypothesis The entropic brain hypothesis by Robin L. Carhart-Harris (2014) refers to a theory which is informed by neuroimaging research that uses the hallucinogen induced neurological state to make inferences about other states of consciousness. The expression "entropy" is applied here in the context of states of consciousness and their associated neurodynamics, while high entropy is synonymous with high disorder. It is proposed that a general distinction can be made between two fundamentally different modes of cognition: Primary and secondary consciousness. Primary consciousness is associated with unconstrained cognition and less ordered (higher-entropy) neurodynamics that preceded the development of modern, normal waking consciousness in adults. Examples include the psychedelic state, the rapid eye movement sleep (REM) state or the onset phase of psychosis. Secondary consciousness is associated with constrained cognition and more ordered neurodynamics. Examples include normal waking consciousness, the anesthetized or the depressed state. The theory further proposes that via pharmacological induction of psychedelic substances psilocybin, the brain is able to enter into the primary state of consciousness (the psychedelic state) from normal waking consciousness. This "phase transition" between these two fundamentally different poles of consciousness is facilitated by a collapse of the normally highly organized activity within the default mode network (DMN) and a decoupling between the DMN and the medial temporal lobes (MTLs), which are normally significantly coupled. The DMN is closely associated with higher-order cognitive functions such as supporting the neurological basis for the self (e.g. self-reflection, subjectivity, introspection), thinking about others (e.g. theory of mind), remembering the past and thinking about the future (e.g. episodic memory). Task-positive networks are associated with the inverse
