Aura's have always fascinated me, I believe that we see them naturally as children but as we grow up and people keep telling us that they don't exist we start to lose our ability to see them.
Have you ever met anybody for the first time and immediately liked or disliked them? I am talking about before they speak to you, before you categorize them by their clothes or looks, it is just a feeling. The person has a good or bad energy to them - you might really be seeing their aura. There are some people that you want to get close to and some people just make you uncomfortable.
This morning I was taking a bath and I noticed how much better I can see my aura in the water. I could see yellow, turquoise and pink. I played around to see if it was just shadows but I don't think it was.
