The shattering glass is one instance of a much wider phenomenon that can be referred to as Life Response. In this case the response is to a thought or mental image. It can also be in response to a feeling, urge, sensation or subconscious formation. The laws governing life response are complex but can be understood by careful observation such as that you report in this striking incident. In my own case, yesterday a 46 year friend was telling me about how he prayed intensely when he was in 8th grade to reverse an error he made in a final exam, but found to his disappointment that his prayer apparently failed to achieve the desired result. After reporting this yesterday he had a call from a young Indian woman who knew she had done poorly in a final exam because she had only answered 60 percent of the questions and knew she had answered some of them poorly. She called after learning that out of the 60 percent she answered she scored 99 percent correct, which under the Indian system turned out to be an acceptable grade. This news came the day he reflected on an incident which occurred 30 years earlier. For an indepth exploration of this subject, see
