Pretty straight forward. A post from another thread has me wondering exactly what this means.
Anyone?
It can be referring to several different things:
1. Political ideology. For example it is popular today to survey the population to find out what we are all thinking, what demon possesses us currently.
2. Illness which acts through invisible contagion: plague or a cold
3. Madness or other mental illness
4. The departed ghost of a dead person who somehow influences, talks through a person such as through a medium. They should be dead but they are influencing the living, instead. In many parts of the world there are stories about this happening. Usually they are scary stories.
5. A song stuck in your head or thought or crush. "I can't sleep, because I'm in love with this girl."
6. An aspect of your personality. There may have been ancient practitioners of meditation who faced aspects of themselves as if they had identities. I cannot verify this, however I have posted a documentary video about it. Possibly then somebody could say 'Demon' and be talking about their pride or their fear etc.
