In this paper, an adaptive network model is presented for working mechanisms and risk factors of sleep paralysis with and without hallucinations. Sleep paralysis is a mysterious phenomenon where a person is awake but not able to move. Correspondingly, people can experience hallucinations and if so, often in a horrifying manner. The introduced network model covers the potential role of serotonin, temporoparietal junction, amygdala, 5-HT2AR receptor and covers the influence of risk factors as sleep deprivation, alcohol use, and the HT2AR gene.@en
