Yeah from what being sleep deprived and sleep disorders, as well as other problems can cause symptoms similar to Schizophrenia and Psychosis. I have done what you did too. I have also hid in my closet or beneath my bed in fear of being hurt. And in the case of loud auditory hallucinations, I have covered my ears and head, especially if it is loud voices or loud banging or explosive sounds. It is really annoying and frieghtning at times. I have sleep apnea and insomnia and sometimes I wonder if I have another sleep disorder I am unaware of. It doesn’t happen every night, but it happens a lot.
