I have come to the conclusion that thoughts are mostly sight and item related. In other words every time we see something, we associate it with an esperance we've had, and a thought is born. I don't think so. I believe that most of our thoughts are partly ours and small parts of other peoples thoughts. Sometimes you don't even think for yourself, but read all the thoughts of other people that are in the room.
Thoughts are like anything else, small parts of energy.
The closer you are to someone else the easier it is to pick up on them, but distance is not always a factor. I was just about to call you. Or have someone else say just what you are thinking. This happens because all you think is not your own. I also believe that time play no part of this.
