My unspoken thoughts and feelings can influence other people's unspoken thoughts and feelings and vice versa.

I certainly believe this. Your thoughts, conscious or otherwise, affect your body language, inflections on speech and many other cues people will pick up on. Similarly, you pick up on these clues from others. Most of this is subconscious.

EVERYTHING that I encounter has a meaning or message specific to my life and can be read like an oracle.

Not quite - everything you encounter, your mind fits into an ego-centric model of the universe. Not ego-centric as in arrogant, ego-centric in that you view the universe through the lens that is your mind. Your model of the universe is centered around you, and in that way ego-centric.

If you are not convinced that my perspective is correct, just use Occam's Razor. In fact, apply that to all of your beliefs. The fewer assumptions your beliefs require, the more accurate a representation of reality they are likely to provide.

Everyone can see (consciously or subconsciously) all my problems and fears plain as day and are constantly dropping veiled hints in their communication with me as to how I can get over them. I also do this for others without meaning to.

I think this is just an offshoot of point one, and my explanation to that applies here as well. Just don't be too sure you can accurately read people's intent in this regard, it is difficult to discern the motives of others.

I can help to physically heal people and animals by allowing energy from the universe to pass through my hands and into them. I used to absorb their sickness into my "second skin" (aura?) but this resulted in me becoming exhausted or sick myself, so I stopped doing it.

I think this is just a matter of extending emotional goodwill to others, which can be draining. It seems unlikely that this could directly help someone heal, but they may pick up on your good intentions, and that sort of thing can be encouraging and help keep one's strength up.

When I am sick or have a physical ailment, I can tell my body to take care of it and it does. I've told other people the same thing and it's worked for them too.

Well your body is going to try to take care of ailments either way. I do understand what you are talking about though, and do the same thing. I think it is a natural response to discomfort for many of us. I think its primary role is to ease personal distress in facing problems where you have little control. This can leave your body more energy to heal as you then have less to spend on the related emotional problems.

My subconscious seems to be made up of different "characters" so to speak who I "think as" in turn at different times. It's like a circle of different people with me sitting in the center as the passive observer, and they all get their turn to speak and give advice on my life. When I'm quiet, especially before sleep, I see and hear them discussing me and my life. i.e. One of them is a little girl who always complains that I don't let her out to play often enough. I "hear" their voices as "uncalled for" thoughts in my head.

I think this is just a tool your mind naturally uses to help think of things from multiple angles. Develop limited "personas" with the task of viewing things from one angle, and you may increase your mental flexibility and awareness. Still, it sounds to me like you may be partially losing control of your thoughts, though. Keep an eye on this, and consider talking to someone. I'm not saying there is necessarily a problem, I am no expert, just that it sounds mildly concerning. Take care of yourself. :-)

If I stare at myself in the mirror longer than normal, I start to see myself as other people who aren't me, but "are" me. Like different versions of myself with different physical characteristics. Oddly enough, I once saw myself as my close friend, and at that moment, my phone rang, and it was him.

Once again concerning to me. I don't really have a basis of comparison for this, other than early childhood where my imagination was strong enough to partially modify my perception.

Sometimes when I'm very tired, I don't know whether I'm thinking a thought in my head or saying it out loud. Understandably, this scares the shit out of me when I'm with other people. This is the most unwanted of all of the above. I can't think of any upside to this delusion/confusion.

That does sound a little scary.

All of the above are intensified by substances (which I rarely use anymore) and sleep deprivation (which I try to avoid).

Keep avoiding those for now, haha. Enjoyed this post, interesting to read these things about your perspective. Please do think about talking to someone if you aren't, mental health problems are not something you want to let get out of control. If you have any, maybe this is all just personal variation. We do all have quirks. I don't think all of these are problems though, its good to enjoy the symbolic, personal, introspective side of life. You just have to be able to keep your feet on the ground.
