This morning cyril asked me to find a website that shows weird coincidences. Then I stumbled across the concept of synchronicity. Wikipedia defines it as:

Synchronicity is a term that was used by the Swiss psychologist Carl Jung to describe the alignment of universal forces with one's own life experience. Jung believed that some (if not all) coincidences were not mere chance, but instead a literal "co-inciding", or alignment of forces in the universe to create an event or circumstance.

Jung's most well-known example of synchronicity involves plum pudding. He tells a tale of a certain Monsieur Deschamps who is treated to some plum pudding by his neighbor Monsieur de Fortgibu. Ten years later, he encounters plum pudding on the menu of a Paris restaurant, and wants to order some, but the waiter tells him the last dish has already been served to another customer, who turns out to be M. de Fortgibu. Many years later, M. Deschamps is at a gathering, and is once again offered plum pudding. He recalls the earlier incident and tells his friends that only M. de Fortgibu is missing to make the setting complete, and in the same instant the now senile M. de Fortgibu enters the room by mistake.
