What is your question, specifically?
If the question is "is it real", than the answer is "probably". I'm not going to say that everything you see and feel means what you think, but it almost certainly is related to something. A mirage in the desert may not be water, but it does indicate something.
If you are asking for more information on any of those individual things, that I can give you. Dreams of the future happen somewhat commonly but are usually hard to interpret. Basically, it is like looking from inside the world to a place outside the world where everything is bigger and more complex and then from there looking back into the simplified context of this world. The best way to learn, that I know, is to look for "anchors of significance" and to be very honest about when you are wrong.
Seeing auras is something that I have less personal experience with, but do know some things about. One clue for you is that auras don't correspond with emotions, emotions correspond with what auras relate to. Specifically this is a person's "direction" in life, or their way of being. But it isn't a one way effect; an angry person is more likely to focus themselves one way while a happy person is more likely to be focused on other things.
The "feeling auras" is actually more of a feeling of how they are at the current moment, which is much more focused on emotion than the auras that you "see" are. The the type of "healing" that you described is like the other side of the same coin where one side is receiving and the other side is sending. The main point of advice I can give is to not wear yourself out in the use of it. Everything you take in and everything you give out has an effect and lacking temperance can lead to disaster. That doesn't mean to not exercise your abilities or to grow stronger, that just means to recognize that you aren't an unlimited sponge or an unlimited battery, eventually you will reach your limits if you aren't careful.
As for the other healing you described; it could be related, it could be completely different, or it could just be just a coincidence as you described. A single incidence is interesting enough to look into it more, but not enough to draw any definite conclusions.
As for the zodiac stuff you mentioned; throw it out and try to pay it as little attention as possible. The real danger is in the fact that it only has the power that you give it through belief. The power that it gets through belief is to /restrict/ your growth to fall within the bounds of its description or to follow the path that it describes. And once this has been accomplished much worse things can grow out of the superstition that it requires as well as the way that it twists your growth away from how you were meant to develop. The type of trial and acceptance that allows you to recognize the experience of seeing auras and healing makes this type of deception particularly potent.
As for myself, I am a Christian who tries to live the life of someone who is called to live a life reflecting God as I grow closer to Him and get to know Him better. I do recognize the power that witchcraft has, but I also know where that power comes from and understand what holds it together. I know the deception and manipulation that is inherent within it and I know he limitations that it has that push people into worse and worse places the deeper that they go. In my experience there is absolutely no reason to use it for anything, especially since the power that comes from being close to God is so much better and so much more complete. But here is the catch: if you come to the true God seeking power than you will likely get very little or nothing (though it still remains his choice), but if you come to Him seeking to know him than you will grow in power and ability no matter what you do. You can't manipulate the Almighty God by offering Him your allegiance, nor is there anything you can do to try to make a deal with Him to get anything.
I know this is late, but please do let me know if there is anything I can do to help.
