exist. At the same time, he was aware that he was thinking, and he was able to contemplate his own thoughts. Scientists call this reflection on one’s own thinking “metacognition” – a skill that so-called lucid dreamers have, as well. Elisa Filevich and Simone Kühn at the Max Planck Institute for Human Development in Berlin are studying which brain regions are particularly pronounced in lucid dr...

BACKGROUND Recent reports by our laboratory have indicated that lucid dreams may be linked to psychiatric conditions, including Attention Deficit Hyperactivity Disorder (ADHD) and other Reward Deficiency Syndrome-related diagnoses. In the latter case, it has been our observation that such lucid dreams can be unpleasant and frequently terrifying. CASE PRESENTATIONS We present four cases of a d...

This paper describes a new scheme for building static search trees, using multiway radix search trees. We present this method for code generation of switch statements in imperative languages. We show that, for sparse case sets, the method produces faster code on average than existing methods, requiring O(1) time with a small constant for the average search. We then apply this method to the prob...

We describe work in progress on a method for determining the dimensionality of Lucid terms. This method gives a better (i.e., lower) upper bound on expressions involving function calls than the method currently in use.

Introduction. We apply the theoretical framework and formal model of the observation tuple with the credibility weight for forensic analysis of the IDS data and the corresponding event reconstruction. Forensic Lucid – a forensic case modeling and specification language is used for the task. In the ongoing theoretical and practical work, Forensic Lucid is augmented with the Dempster-Shafer theor...

In a lucid dream, a dreamer becomes conscious that she can interact with and control events in the dream environment. Using gestural control devices and responsive video visualization of vocal interaction, our interactive performance, dream.Medusa, invites four participants selected from the observing audience to experience a simulated lucid dream. The participatory nature of the dream.Medusa p...

Recent studies suggest that lucid dreaming (awareness of dreaming while dreaming) might be associated with increased brain activity over frontal regions during rapid eye movement (REM) sleep. By applying transcranial direct current stimulation (tDCS), we aimed to manipulate the activation of the dorsolateral prefrontal cortex (DLPFC) during REM sleep to increase dream lucidity. Nineteen partici...
