I dont understand what this could mean?
If anyone has any ideas help me out

Hi,
first: my english is not the best I'm from germany so excuse me  

I've had a dream exactly like yours, my friend stabbed me with a knife. In my dream I was all over with blood and he was laughing.

Then weeks later he break up with me and i found out that there was another girl. Sad situation, but that is what I can say to your dream because I've had a similar. And that doesn't mean that that will happen to you. But I think that such dreams have a meaning and in my way my subconsciousness give me a sign. Whatever, I hope my answer is okay for you and a dream mustn't have a special meanig, sometimes its only a dream    Good luck!

How has he hurt you?
As said above, your subconscious could be warning you that he is going to hurt you in some way.

If you have the dream again....look at the details, his face, the knife, size, etc....
Its obvious you are feeling attacked on a subconcious level.....It could be anything....it could also not be your be your boyfriend, but someone you identify with on that level.
Only you know what bugs you.....look there first

Everytime I die in a dream its by the hands of strangers, eveil men, I mean really evil.
Never have I been killed by a loved one....
Interesting...yes?

Thanks for replying to my post
I will take all of your ideas in consideration
Thanks again :D
