In this paper I consider consciousness as a widespread cognitive phenomenon,representing not only the direct interaction with external stimuli, but also accountingthe way the subject suggests himself of engaging with objects orevents perceived directly or indirectly through recalling passed circumstances.It is plausible to suppose that also dream activity could be linked with consciousnessitself, despite many brain neuro-chemical and functional modificationsoccur. Considering a philosophical approach it is important to verify howthe absence of a first person perspective and a strong subjectiveness (typicalof dream) could affect the flow of consciousness, according to the differentmodalities it uses to show daily life experience. I propose the analysis ofdreaming and waking phenomenology of consciousness and are proposed andcritically discussed three experimental and theoretical models that attributeconscious states to oneiric processes. In the first one Cicogna & Bosinellianalyze how consciousness could be differentiated in sub-elements, operationuseful for its attribution to dreaming activity. In the second one Hobson's AIMmodel divides the oneiric process specifying the neurochemical and structuralmodifications that occur during it. In the last one are pointed out the elementsof the Default Mode Network hypothesis useful to add the neural oneiric substrateinto the DMN, this also to underline the importance of dream's adaptivepotentiality.
