Sleep Recording Device

A device capable of recording data that allow the detection of dream sleep is needed, such as an EEG system or even a system containing multiple devices such as a real polysomnographic system with EEG, EOG and EMG. As suggested by the Theory of Sleep Communication, it seems reasonable to use REM sleep as the preferred sleep communication sleep stage (compare chapter 3). Depending on the device(s) used, the REM detection reliability varies: using only a cheap one-channel EEG, there will be more misclassifications than with a professional complete polysomnographic system.
