Few say that according to psychology if you are thinking of someone voluntarily then he/she will also think of you.. and if involuntarily his/her thought is just coming up in your mind that means he/she is thinking of you..
Anyone knows the details? Or any psychology student here who can explain?

You can found this lines in one of Neville book. Even in psychology you read about this. More you are connect with person stronger is this method. For example: i am very connected with few people. When i think about them they will call me or send me a text. We are all connected to one source so we can even talk through this source. You cam found a lot of theory about this.
