I need your help interpretating my dream!

I was at the front yard at my grandma's neighborhood. I saw some foreign ppl holding big pretzel's with sesame. I asked them where did they bought them from. And they pointed 3 places in the area, one of them was about 20metres far.
I went there on the end of the waiting line of people. I saw i guy i knew and we had a small conversation. He was standing right behind me in the line and as we were talking. I suppose i didn't make eye contact...

And when my turn came, he went infront of me to order, while talking.
Then i looked at him, he had bleeding wounds on the left side of his face, down to his chest. He said that his girlfriend beated him. Because he did something wrong.
I didn't say anything else... i just thought that in my opinion what he did was wrong in some way, but how could someone do such thing...!?

The feeling i had after waking up... i thought about how he may be having relationship or love problems too...
IRL i had feelings for this guy a while ago but he didnt felt the same. Also he doesnt have a gf IRL.
I have some ideas what the dream might mean, but i'm not quite sure, i have no idea what the pretzel's symbolize, also the waiting line and the fact that he took my turn... but i have a slight idea what the wounds symbolize. So i would be glad to discuss it with someone.
What is your interpretation?
