Why did the fortune teller say I couldn't go to the temple to burn incense?

It's hard to explain this to you in Me Before You. But from what you said, it should be because you are psychologically sensitive. Since you were a Taoist in your last life, you can be sure that you should belong to a sensitive constitution. And unlike what we often think now, in fact, temples are not holy places at all. In ancient times, temples were built to ward off evil spirits and kill ghosts, so temples were generally built in places that were considered to be more dangerous and sinister. And you are sensitive to spirits, but you have no special training and are not familiar with the methods of contacting spirits. Natural contact with this place is more dangerous. Of course, I'm talking about the logic of fortune tellers. If you don't think there are spirits in this world at all, you can ignore their remarks. However, who can tell the things in this world? If several fortune tellers happen to coincide, I'm afraid they do have their reasons.
