Our April 2022 paper on the possible role of dream-sharing in social evolution and human self-domestication.

We have published a follow-up to our papers on dream-sharing and empathy proposing that in human history and pre-history the sharing of dreams contributed to the social evolution mechanism of human self-domestication. This mechanism has been proposed to lead to reduced emotional rectivity between people, greater empathy, and group bonding.

Our empirical papers that this was based on are here (open access article in Frontiers in Psychology, 2019) and here (in the American Psychological Association journal Dreaming, 2021, not open access).
