Scared

Okay, I take psychology in school and today i read this article in the book sayiong that dreams alot of times mean you are expressing fears of the past, future, or present. I didnt think anything of this dream i had last night until i read it. Im scared it will come true and i don't want it to. How would you feel to walk in a room and seeing one of your best friends comiting suicide? I freaked(not noticable by people that dont know me) and one of my other friends asked me what was wrong and i told her.She said that I had a right to be worried but didnt say much else cause the bell rang and i don't know if i should talk to the friend this is about...HELP.
