Re-defining discontinuity: Implications for the functions of dreaming

Hobson and Schredl’s dialogue (2011) raised important questions concerning the operationalisation of continuity across sleep and wake, especially in contrast to discontinuity, and questioned the potential functionality of such continuity. We expand on these issues by focussing in particular upon the incorporation of different kinds of waking life experiences into dreams as both a methodological tool and a means by which the function of memory consolidation processes in sleep can be better understood. By drawing upon a theoretical framework of autobiographical memory, we propose that “discontinuity” needs to be operationalised carefully, and that a conception of discontinuity across sleep and wake can still provide insight into, and evidence for, underlying mechanisms of consolidation.
