Evidence of this occurred after Roger Bannister managed to run a four-minute mile. For thousands of years, people tried to accomplish this feat, but as soon as Roger Bannister did it, a barrier was torn down and a dozen did exactly the same as Bannister shortly thereafter. Sheldrake says, for example, that through morphic resonance, people doing the crossword puzzle in the evening find it easier to do than the people who did it in the morning when the paper first came out, because there had already been an impact on that particular morphic field the answers had been deduced by others. What I've said in my books is, because one can project thoughts into people's minds and because one can move one's subtle body into the force field or physical body of another person, we cannot categorically say that all the thoughts we have are ours. In the extreme case of mass hysteria or collective hallucinations, for example, you can see how ideas jump so rapidly that instantaneously a group of people can act completely irrationally.
Fear can also jump from one person to the next.
If the person next to you is scared, it makes you feel uncomfortable and insecure. You can test this for yourself by getting on any airline flight that has a lot of first-time flyers, or vacationers who are not used to flying often. The fear you feel as you walk through the plane is intense, and it jumps back and forth between the passengers, affecting all of them. Yet in the coach section, it's more intense than, say, in first class, where there's usually a sense of tranquility. This is because there are fewer seats and they're spaced farther apart.
