Dream About Boyfriend Train Accident

U can't remember much... I think i was going to school and my boyfriend to work. Then i got a call that there has been a big train accident in the city. Somehow i got a letter from the doctor, saying that my boyfriend passed away in that accident. A classmate of mine got the same letter, her's saying her boyfriend is slightly injured. We talked about it a bit and after school i went home. I dropped off my bag in my flat and walked down to the courtyard where the big tree is standing. I hung myself on that very tree that day. I woke up almost crying.
