I just... had the weirdest acquaintance on the train and I'm really scared

So, I met somebody in front of the train station, person A. They were just waiting for the station to open like me. We talked for a bit and they were alright. When the station opened, we walked up to the platform where we met Person B. They asked us if the triangle stopped at $my_stop, we said yes and they got on.

They sat down next to Person A and me and started talking. They just seemed like a really chatty person at first which, while being annoying after being awake for ~22h, would've been fine.

But then they started talking about having spoken to god and having met Lucifer? Person A and I, despite having met for the first time 5 minutes ago, pretended to be /really/ good friends and tried starting conversations several times but Person B kept Interrupting us to talk about some really gruesome things like "oh yeah you can still go to heaven if you've killed somebody, you just have to regret it afterwards"
