About every second person experiences at least one traumatic event during lifetime, with prevalence rates in Europe between 54 and 60.6% (Atwoli, Stein, Koenen, & McLaughlin, 2015). After experiencing such an extremely disturbing and often life threatening situation many people will exhibit sleep disturbances, and among those who develop clinically relevant post-traumatic stress disorder (PTSD) up to 90% describe one or more sleep-related symptoms, for example difficulties to fall asleep or maintain sleep, early morning awakenings or recurrent nightmares (Harvey, Jones, & Schmidt, 2003). Recently, also a construct called fear of sleep (e.g., because of nightmares or the feeling of loss of control) gained increased attention within this concept of trauma-related sleep disturbances (Pruiksma et al., 2014). However, basic knowledge about the underlying mechanisms of sleep disturbances in PTSD (e.g., fear of sleep) and the temporal relationship between sleep-related symptoms and PTSD symptoms are still lacking (Babson & Feldner, 2010; Cox, Tuck, & Olatunji, 2017).

Our group is currently conducting a series of studies investigating fear of sleep as specific characteristic of trauma-related sleep disturbances, partly in collaboration with Prof. Dr. med. Martin Sack (Klinikum Rechts der Isar, Munich).
