When It Rains

I was thinking about the idea that particles of mass are attracted to each other through the force of gravity. Often it seems events are the same way. We often seem to experience several bad events or good events in quick succession. Of course, it's probably just coincidence or our perception, but what if events have a "physical" effect on time (if in fact time exists)? What if certain kinds of events are more likely to cluster the way matter adheres to itself? I would like to see someone develop this idea further.
