Creepy dream

I was riding a train with a woman who was older than me. I am not sure where we were going. Suddenly there was another train on the same track headed directly towards us. I was panicking and trying to get my companion to do something but she didn't seem bothered. I pressed her on it and she says "...I'm dead." So then I start panicking that I will get hurt and she tells me "....you are dead too." So I was like "oh...ok."

The trains collided and sure enough we were absolutely fine. I felt relieved that I was dead and didn't remember having died.
