Well, they aren't auras exactly, but I can see... light bending around the object. It's like I can see a current of light bending to the contours of an object. It is very very faint, but this "aura" looks different from all of the other light in the room in the way that it appears distorted and adjusts to the contours of the object perfectly. This most often happens with trees and sometimes people. I don't know if this is an optical illusion based on how light is percieved and how light rays actually bend, and how the retina processes all of this, but I've been able to see this since I can remember. I can't recall seeing this with non-living objects though, so it doesn't agree with your towel story. Also, sometimes I see these "auras" and sometimes I don't. I can't really control when it happens, it just does.
