Very Very Disturbing Dream

Last night i had a dream where one of my friends committed suicide by jumping into a well ,Now its not odd for me to dream about my friends dying im very used to it

But last night i had a dream where me and my friend were sitting on a wall
And my other friend was beside a well
For some reason i knew and so did my other friend that she was going to die
then all i remember is my friend beside well saying she wanted to die and she jumped head first into the well , All i did was turn around gave my other freind a hug and started crying

Now im not very easily disturbed by my dreams but this one had an amazing effect on me and frightened me allot

What does this mean ?
