Introduction. Sleep paralysis is a REM sleep parasomnia characterized by the inability to perform voluntary movements while the person feels awake and conscious of the surrounding environment. Recently, it has been demonstrated that it is possible to determine the exact onset of a sleep paralysis episode by instructing the dreamer in advance to perform a pre-agreed eye movement, which can be observed in a polysomnography recording. In this study, we present the results obtained from the analysis of the signal obtained during a sleep paralysis episode.

\nMaterials and Methods. The participant was instructed to move their eyes from left to right three times when experiencing a sleep paralysis episode. A standard polysomnography was conducted, and the obtained signal was subjected to bandpass filters from 0.16 to 65Hz, a 50Hz Notch filter, and ICA filters. Spectral power density was analyzed in frequency bands of interest during sleep paralysis episodes, normal REM sleep, wakefulness, and NREM stage 1 sleep.
\nResults. During the episode, there was an increase in power density in the alpha (8-13Hz), beta (15-30Hz), and gamma (45-65Hz) frequency bands compared to normal REM sleep. On the other hand, power density during the episode was similar to NREM stage 1 sleep in the theta (4-9Hz), alpha (8-13Hz), and beta (15-30Hz) frequency bands. In comparison to wakefulness, power density during the episode was lower in the alpha (8-13Hz), beta (15-30Hz), and gamma (45-65Hz) frequency band<\/p>\n","protected":false},"excerpt":{"rendered":"
