^ A few more data points:
(5) Several years ago, I became suspicious that demons were brainwashing me in my dreams at night, because I would sometimes catch them red-handed (apparently). I have never been a church-goer and usually I am sort of agnostic, but I have had several strange experiences in my life that have made me susceptible to magical thinking. I was somewhat addicted to alcohol. I was constantly sipping a drink from sun-up to sun-down at that time in my life. Suddenly I decided to stop drinking and also abstain from masturbation. It seemed surprisingly easy, but then a couple of weeks later, I went to visit a friend, and I became psychotic. I am still trying to get back to my old self today (5 years later). ... So I have wondered if abstaining from sex contributed to the breakdown. I don't remember any particular difficulty, but who knows. I had not actually started abstaining from alcohol yet. I had stopped drinking for a couple of weeks, and then I drank a lot over the weekend with my friend with the intention of quitting permanently afterwards.
(6) Those demons in my dreams that I suspect might exist seem to be connected with addictive behaviors (alcohol and porn) and depression.
(7) I have the tendencies to "delusional disorder" that makes magical thinking an issue, so the demons in my dreams may not be good for me to believe in.

Sorry, I know that some of the things I say sound wacko. I don't actually believe them most of the time, but sometimes I do and they can become distracting and distressing.
