Why did the fortune teller say that I can't visit patients? I did. Two days later, I sprained my ankle. What logic is this?

You say this because you acquiesce that fortune tellers are spiritual. Ever since the fortune-teller told you, you have kept it in mind, blaming all the bad things that happened after seeing a doctor on you, because you went to see a patient. Actually, if you think about it, it took you two days to sprain your ankle when you went to visit a patient. There is no causal relationship between the two.

Maybe you walk carelessly because you are always worried about what will happen.
