My 2nd cousin died and came back to life. He’s a completely different person.

My deceased cousin’s parents were in a cult. There’s a guy in the cult who said that he can heal people. In 2015, my cousin had a terrible accident that caused him a stroke and he fell into a coma. The cult guy said that if we spend the night in a place with many cows, my cousin would come back to life. My family spent the night in a place with lots of cows and many people from the cult were doing some weird rituals. My cousin woke up. But he is a completely different person. Before, he was very sweet and had a good sense of humor. Now he’s imperturbable. It’s very weird. I don’t know what they did. But it seems to be real.
