Help Identify This, curiosity Options

First off this is not spell-begging. Merely a beginner wondering if experiences he’s had might be something more than just his mind playing tricks on him.
I have a couple of questions regarding the extra senses that I have been hearing about and, being new to sorcery and everything herein, I am curious whether or not the things I am about to describe are anything special, or anything at all. Most of them I can describe using simple physiological responses. However I do have to ask myself if they are indeed something and that I am just pushing them off as being imagined. The main problem I guess would be my inexperience with the craft however philosophical I may have been in the past.
The first of these feelings or experiences that I am curious of, is something I have to this point classified as a neurological phenomenon that results from the bodies electrical system sending out a discharge of pent up energy. That would be the basic description. What happens when such an experience takes place is basically sent from working the back muscles, to get too descriptive here would be rather difficult because I am not exactly positive how it works, sometimes I can do it other times I cant, the main muscles in use are the shoulders and middle upper back, and the lowest back muscles. The result of enducing this reaction is basically the same as what I could call, “getting a chill” a surge of feeling is sent out from the back to other areas of the body, all except for the head and torso( the back is the exception). A visible physical response to this is the hair on whatever limb that it goes to will stand on end then sit back down after the surge passes. The only available example of how I think it might work, and I do emphasis the word think, is something similar to that of the electric eel. I have worked with this for some years now and have found that I know very little about how to develop or really control when this energy is stored and can be released.
The next one has to do with sight. I won’t try and pretend that my sight is 20/20, to be honest one eye is close and the other is 20/400, however I have done the best I can to help learn to focus my eyes at will, and have had an innate ability to do so since I was a small child. The question I have on this is, I can get my eyes to a certain point were it seems I can see the air particles and the movement of them, not movements as in wind, but see the air itself. The other aspect of this aspect of my vision, is that when I focus on an object, normally a person, but many inanimate objects as well, it seems as there is a fine invisible line that becomes visible between the air itself and the object, sometimes I think that it is possible that I am seeing colors with this but that is something that I don’t know yet, it is difficult to tell, sometimes it could be a color around it that is messing with me, or a glare of light on the object. This may not make much sense but this is still relatively new to me as in the past few years only, and I haven’t worked with it that much, but it is just a simple question I have.
I am definitely not well versed in the meanings of many things, or in what abilities are or how to tell when you are using them. However any help for the questions I have posted would help inform me of where my progression level is on some planes. Thanks in advance for the help.

To the first one, the same thing happens to me, but I can't explaine it. I've learned to control it and can perform it at will, and it feels very good, but I have no idea what it is and I'm curious too.

The second one, however, is easy to expline. You are simply seeing the aura of an object. The far-sightedness of one of your eyes combined with concentration and focus and regular vision of your other eye has trained you to see auras. Seeing the particles in the air... I'm not too sure about that one though and that happens to me as well.

Try staring at your hand for a few minutes until your periphrial vision darkens (this is key) and you should see a much thicker and wider aura than what you normally see.
