This book surveys the current science of dreaming, and then details methods, case studies and theories of the use of dreams in psychotherapy. We are honoured that two artworks from DreamsID are reproduced in Chapter 9, Avenues of Exploration: Visual Art and Technology, and that the theory and practice of the DreamsID art science collaboration are described in that chapter.

One of the aims of the DreamsID collaboration is to increase empathy towards the dreamer through the discussion of the dream and through the discussion of the artwork depicting the dream. We have now published the first study on the relationship between dream sharing and empathy, in the journal Frontiers in Psychology. The paper can be seen and downloaded here.
This paper addresses how long it takes waking life experiences to be incorporated into dreams. Personally significant events are found to have a different timescale of incorporation than major concerns and the more everyday activities. This provides evidence that dreaming has some emotional processing and memory consolidation function.

Blagrove, S. Hale, J. Lockheart, M. Carr, and A. Jones, in Basel this September.
A new theory of dream function: Telling dreams enhances empathy towards the dreamer
Mark Blagrove, Michelle Carr, Alex Jones, and Julia Lockheart Presentation summary: We propose that dreaming has been selected for during evolution so that the fictional emotional simulation can be told to others after waking. The benefits of the simulation to the dreamer occur not during sleep but due to enhanced interpersonal bonding and, in particular, enhanced empathy towards the dreamer. A paper in the open access journal PLOS ONE, published October 2017, addresses the timescale by which daily life events are incorporated into dreams. The majority of these incorporations are from the days before the dream, and, as noted by Freud, mundane and apparently unimportant memories from the day before the dream are also incorporated.

Authors are Raphael Vallat, Benoit Chatard, Mark Blagrove and Perrine Ruby. An April 2017 paper might lead to work that gives clues as to whether dreaming has a function.
F.Siclari et al. (2017). The neural correlates of dreaming. Nature Neuroscience, Nature Neuroscience, 20, 872–878 doi:10.1038/nn.4545. https://www.nature.com/neuro/journal/v20/n6/abs/nn.4545.html Francesca Siclari and colleagues woke participants hundreds of times in the sleep lab and asked each time whether they were having a Dream Experience (DE), Dream Experience Without Recall of a dream (DEWR), or No Experience (NE). They found that Brain activity associated with Dream Experience (DE), as compared to NE (No Experience), had reduced power in the 1–4-Hz band in a parieto-occipital region, that is lower amount of slow waves, which are associated with non-REM sleep. DE with recall of content, compared to DEWR (Dream Experience Without Recall) and NE, was associated with higher high-frequency power (more wakelike EEG) in medial and lateral frontoparietal areas. So dreaming occurs in NREM sleep because the 'hot spot' is activated. The next step would be to find out why the hot spot / dreaming, is turned on during sleep, and indeed during REM and non-REM sleep. We could ask the question, is virtual simulation of the world (i.e., dreaming) sometimes needed to complete/enhance memory processing that is occurring during sleep? Does the brain do some memory processing and then need to run a dream simulation to complete the processing? Also, if we can find out why the 'hot spot' changes during sleep, with deep slow waves decreasing and fast waves increasing, that might give clues as to any function of this physiological change, and any function of the dreams that are then created. The beneficial effects of discussing dreams are described in the following two papers:
http://journal.frontiersin.org/article/10.3389/fpsyg.2013.00979/full and http://journal.frontiersin.org/article/10.3389/fpsyg.2015.00831/full In these studies dreams were discussed for about 40 minutes and the discussions resulted in high levels of insight about the memory sources of the dream and/or insight about the dreamer's waking life. In soon to be published work we are comparing outcomes of such discussions of dreams to discussions of daydreams. Many thanks to the Bial Foundation for funding that work. The results and background rationale for the study were presented at a public event at the Freud Museum, London, on 20th March 2016. In all this work the outcomes of considering dreams were assessed just after the discussions. One of the aims of DreamsID is to investigate whether the consideration of a dream and of an artwork based on the dream, has beneficial personal outcomes across many months after the artwork is produced. |
