As this is the Dreams and Dream interpretation category, the following answer will address the question.
The question appears to ask about a dream in which the dreamer is the boyfriend of a girl who is the "crush" of the dreamer's friend. If that is the case, then the dream suggests that the dreamer admires the girl, or at least respects his friend's choices. The dream does NOT indicate that the girl has any attraction to the dreamer, and it does not mean that either young man will have an actual relationship with the girl in the future.
You are afraid that your friend has the same feelings with your crush and not literally your friends wanted to kill anyone...
It means that you want to be a part of your crush's life. The dream only illustrates your own emotions. It does not tell you anything about how the guy feels about you.
you have a fear of being let down by people you admire
