Usually when you de-possess a person, what do they relay to you? Do they say that they could see it, they could feel it inside them, they could hear voices?

They do tell me exactly what they go through. They feel like killing themselves. They feel like completely a headache or a migraine or completely violent. They just want to bang their heads or harm themselves or probably even commit a suicide. I have to know whether this is a demon of suicide or whether it's a demon of depression or is it a result of any dark magic that's done upon this person? Once I identify the demon, it's only then that I can counsel him and I can let him get out.

Are there weaker entities that actually latch on to a lot of people in the city and they don't even know that something has latched on to?

Of course. There's a common misconception that if I'm demonically possessed, it's not necessary that I manifest physically like this, like a mad person, turning my eyes and climbing walls. A demon might possess you and you might experience a lot of misfortune in your life, experience a lot of accidents. Whatever you venture in will not bear fruit. There can be a lot of fights in the family as well. So these things happen.
