I believe I started doing this in 7th or 8th grade. It doesn't happen as often as it used to. Except the other day when I was on the computer.
All in all, I can see people through the computer... Without using a webcam.
For example, I was talking to my friend Charlie (fake name) online. I believe we were role playing, but that doesn't matter. All the sudden, I got this spontaneous vision of Charlie scratching/rubbing his nose. That used to happen often, not much anymore, as I previously stated. There has been other times where I have done it on purpose. (Another example)
I was talking to my friend Shane (fake name) online. I had one of the spontaneous visions of him leaning back in his chair, rubbing his face. He jokingly called me a "stalker." (Which would be impossible, since he lives in a different state.) Anyways, he began asking me questions that I was getting correct. One of the questions was, "What's the color of my boxers then?" I concentrated, and got the color blue in my head. I said blue, and I think I creeped him out.
There was another time where I have guessed another internet friend's clothing. She was wearing a green t-shirt and blue jeans. Details on a shirt, for example, are kind of hard to see.
So... Am I somehow psychic? I do have a great grandmother that was a Strega, so I could see where I might get it from if I am.
