Alright. I started to communicate with it before you posted it that. I asked for it's name and I heard "Ball" Not sure if it's spelled like that but that's how it sounded.
It sounds like Bael, a pretty "top brass" sort of demon. Lower levels or personal lieutenants of certain networks tend to use their leaders name as a handle. Wheither its for intimidation or just a policy of sorts I don't know but I've seen it done quite a bit by people who've never even heard of him. It could just be something else but you can google Bael if you'd like to see if any of the pronunciations and variations sound familiar though I wouldn't say this is definate.
First I would like to say that I'm not arguing against any spiritual theories that have been put forward and I think it's a possibility that cannot yet be ruled out but let me perhaps suggest a different perspective.
From the perspective of a medical practitioner, if I had seen you in clinical practice (and I have seen several patients with very similar experiences) I would ask the following:
1) Have you been withdrawing socially? Have you been less productive at work or in class?
2) You mentioned that you took time to sort out mental issues. What were these issues and have you seen a doctor, psychiatrist or psychologist?
3) Do you have any medical illnesses? Are you on any medication?
4) Do you have a family history of mental illness?
5) Have you noticed any slowing in your thinking, speech or actions?
6) Do you feel scared and worry that people are out to harm you?
I ask these things because you mentioned some mental issues and what you described were classic positive symptoms of schizophrenia. I don't want to alarm you and I'm not saying that it's impossible that a demon many involved, I just think that if you're worried about your mental state you should see your GP or a psychiatrist for a formal evaluation. Maybe this would give you some clarity.
I have been the same socially, since school has started I've become more social because I can see most of my friends in one spot now, I was attending to my mental needs for attempted suicide. The only medical problems that run in my family is depression, I am also taking Zoloft. I do get a paranoid feeling every now and then, but it's the look over your shoulder feeling, but nothing that terrifies me. I have only recently become more paranoid within my own home because of what has been occurring. Outside of my home I feel great, but at home I occasionally get uncomfortable, like I'm being watched. But my mental process is same as always and I'm doing good in school, so no change there either.
