Wow, I've never heard of anybody else having that electric shock feeling, I thought I was alone on that lol. It hasn't happened in a few years, but occasionally I would get what felt like waves of electricity shooting up and down my body. When someone was with me during one of these episodes, they could actually see the hair on my face and scalp stand up as the electric feeling reached my head. Once I had one while I was playing a video game and the car I was driving began making turns on its own, without my fingers even touching the controls! That may have been a coincidence, but it never happened before or after that incident.
Personally, I think us social phobics have some kind of 6th sense that makes us aware of some aspect of life that nobody has been able to term or explain yet. Have you ever felt like you are ahead of your time? Like you're out of place in the current world? Maybe we feel so strange because we are in a small minority that has a tiny amount of some mental ability that is introducing itself into our race's evolution.
Think about the changes that have taken place in the modern world over the past few centuries. It is only reasonable that our brains continue to advance along with the technology that surrounds us.
Lol, wrap your heads around that you social phobics.
