In the New Testament, in the Book of John (John 12. 29), it describes an interdimensional event that took place at the baptism of Christ, when a loud sound was heard. The interesting part of this experience was that a portion of the crowd of onlookers heard a loud thunder clap, while others heard a voice speaking (which they interpreted as the voice of "an Angel").
Yesterday the sound of angelic trumpets shook the walls of my house, but it sounded like an abnormally loud thunderclap that had effects around the world and was heard by many.
This was the ushering in of a new cycle of experience. It signaled the end of a period in which feelings of guilt and blame and shame suffused many. In this new cycle of experience the main challenge will be to overcome feelings of regret over lost choices and missed opportunities.
