How to create coincidences:
Make a date that you want to invoke fear in or what ever motive. Eg 5-5-5
Add them up and it equals 15.
Now we think of other dates that equal 15. 1-12-2, 5-6-4 etc
At this point you want to look up these dates and see all the events that happend on those dates. The only one's you need to are the one's that can be feared.
There you go, you now know how to create coincidences, superstition and so on.
Good luck.
