My mom and I usually know when one of us is going to call the other. We have no particular schedule for calling, but almost every time the receiver of the call knows its coming!
Also Ive been 'sending' to my daughter since she was little. I discovered this accidently when I randomly thought about a toy or article of clothing and she would always have it by the next day. I would purposely think of toys and clothes she hardly used-as an experiment-and it still worked!
Over the years, I usually know 'stuff' before she tells me, if shes out and she calls, I know its coming and what shes going to ask.
Ive also had many experiences like sanujya wrote about - knowing whats going to happen beforehand. The two that stand out most painfully was when I was sitting on a bench watching and air-hockey match. A thought went off in my head that said-"move, you're going to get hit with the puck".(I was easily 10ft. from the table) I thought, "thats stupid-why did I think that. WHAM! The puck hit me right in the forehead. I've never seen that happen before or since. From then on I always paid attention to these precognitions and have saved myself from other mishaps.
The second one was the mini-van we bought last year. From day one I had a bad feeling that the thing was going to hurt me. (Ive never felt this way about a car before!) I had to ignore this 'thought' because it was our only transportation. Sure enough, one morning it refused to decellerate,lost control on a new gravel road, landed in a ditch & broke my nose and eye socket. This was my first and only car accident.
So, regardless of what any non-belivers might say, its worked for me.
