Energy, Ki, Sense, Aura
Its always hard to explain it exactly, but I can sense multiple things from a person. The first and largest thing is emotions and intentions, then from there I can sense physical health, and finally physical location.
I believe that everything has an energy to it. It doesn't even have to be alive to have energy. It exsists, so it has energy. People and animals (those with the ability to move from place to place of their own choice) have different personalities, different makeups within their own energy. These differences usually define wether the being is more able to absorb one type of energy over another, and that somewhat dictates our likes and dislikes as living beings. A person or animal that is very social and never tires of big groups of companions is more able to capture energy from large groups, they need more than a single other being for their energy to be stable so they seek out others to constantly be with. Others prefer solitude and can gain energy from ob
The people who believe in my ability (there are always disbelievers) usually think it would be awesome to have. It is sometimes. Whats cooler than knowing where your friends and family are in stores when the arrive there 15 minutes before you and could be ANYWHERE? Or knowing when people are getting sick? Or when they are upset or not? But through my childhood, while I had a lot of "wow cool" moments, I also doubted myself a lot. Others doubted me, and I was in a constant struggle to "be normal." I would talk about my ability and people would tell me it was impossible and stupid. There were quite a few times I had "friends" who were being nice to me on the outside, and to anyone around me it seemed like they were friends with me. I let them be friends with me despite the feeling in their energy that I got that told me to push them away because they were only using me for money or items. I would tell myself what everyone else did. That there was no way I could feel what I did, and that this person was my FRIEND. Many of those "friends" later stole items from me, or money, or told me off right after christmas or their birthdays. I would then sit and ask myself how in the world I let that happen? Why couldn't I listen to MYSELF and not everyone else?
The other bad thing is that I am still horribly bad at blocking off what others feel, so when I am around someone who is really upset or mad at me, I can get affected. When my parents were divorcing, my dad lived with my mom and I for a year or so, and I would wake up and eat breakfast and puke it up a few minutes later because of all the tension in the house. I am not quite so sensitive to that anymore, but I definately amplify whats around me and get sick a lot more often than others usually do.
Good or bad though, I think my ability is something that is here to stay, and I can only get stronger for it. I hope to master it eventually. It would be nice to be able to block negative things better, or feel the positive things stronger, but at my own will.
