Recently, Allan Hobson published a brief essay in which he recognizes that lucid dreams are scientifically relevant and constitute a powerful tool for understanding the neurobiology of consciousness (Hobson, 2009). His statements are mostly based on the study by Voss et al. (2009), which employed refined mathematical analysis of electroencephalographic (EEG) recordings to tackle the neural basis of lucid dreaming. Several questions are open in this field, and we address one of them in this commentary.
