earthquakes
I am convinced that if I focus hard enough, I can actually cause an earthquake. This is because I thought about earthquakes a lot in the fall and then we had one. It was a 5.6. I also think that if I think really hard about other bad stuff (like terrorist attacks and genocide) that they will come true. This is not the case with positive thoughts. That would just be wishful thinking.

stand under a projecting ledge or balcony or get into a large old library or book store on the ground floor.
