A team of researchers including Katja Valli and Antti Revonsuo have published an article in the journal Sleep Medicine with the title “Dreaming furiously? A sleep laboratory study on the dream content of people with Parkinson’s disease and with or without rapid eye movement sleep behavior disorder“.
Briefly, the study investigated the dream content of subjects with Parkinson’s Disease (PD) and Rapid Eye Movement Sleep Behavior Disorder (RBD), finding, among other things, that PD patients with RBD had more negative dream content than PD patients without RBD.
