I can feel or sense others' energy. Its hard to explain what I feel about them other than the energy they exude has a certian vibe or "flavor" to it. I can't really tell you what it feels like, other than I don't like being in big crowds because I often get tired and claustrophobic. I think I've always had this ability.
Guess that makes me a, what is it called? An empath? Anyways, I think I can also do something else.
I once had a sore spot on my body, I think an ache in my arm. I closed my eyes and ran my hand an inch or so over that sore spot and focused on it. I could see a dark color in my minds eye, right where the sore spot was. I then began to, well, essentially "pull" at that dark spot, making motions with my hand like I was extracting something from it, without actually touching the spot. As I was doing this, I could see, in my mind, bits of the dark spot being taken away by my hand and the spot lightened up in color and dissipated. The pain then, was gone.
I dunno what that it all means, but I did something, I think.
Onto ghosts. They most certainly exist. There are two basic catogories of entities or spirits. Those who are benevolent and watch over us, or perhaps protect us, and those who are demonic and wish to cause us harm. Sometimes, people unkowningly unleash demonic spirits into this world and they cause all sorts of heck on people. Even violently attacking and maiming them. Other times, people take on dark and vengful feelings after death, through their actions in life, and are themselves, dark spirits.
Don't ever mess with the spirit world. You never know what might happen.
