I have to be very, very careful about this type of thing. "Seeing" auras, or spirits, or whatever is one thing...know what you are seeing is another.
OH! yes I agree... I actually see nothing with my physical eyes...I don't see auras... Only 1 time long ago did I see the evil spirit in someone... I am new to actually speaking out what I see, so I consider myself a novice... I wait, test to see if what I saw was correct...I ask the Lord... I do not go around seeking spirits... or see everyone with an evil spirit...
The problem is, knowing what you are seeing. Are you "seeing a person's spirit" or "seeing a spirit interacting with a person" or "seeing a person's energy field" or "seeing hallucinations".
No, I do not yet see a spirit interacting with a person, or an energy field, seeing Hallucinations is why I am careful, but I had seen certain spirits that I later found out was the truth...
Seeing a persons spirit, that is a good question... The last one Doloris, I believe I saw a witchcraft spirit and all the others that come with it... That's why in a previous post I mention Santaria...
To be honest, I'm a bit afraid of looking more into this because of the direction it could take me.
Well years ago I had many questions relating to demons and tried to research it but the Lord said NO! Several times through several different persons that didn't know me..
This may be your case... perhaps this is not for you, or not for you at this season...
I gave up all of my active abilities when I came back to Christ, but things I've studied and learned to do passively...they are all still there. It's not something I can easily unlearn. This would be a good example of one of those things... Lay it before the Father...

The gift I asked for from the Lord is the gift of great Faith and Healing... Not Disearnment of Spirits...
I do know this, while God can use anyone, and any ability, they aren't necessary, and the ability to see spirits will not bring you any closer to God.
