Can somebody tell me what this dream means?

I saw it some days ago. I was outside my father’s restaurand. It was very dark and no one was outside. I suppose it was 3 to 4 am. So, I witnessed a terrible motorbike accident. The bike was one of those big and powerful ones. The man that was riding the bike fell and it looked to me that he broke his whole body! The man to me was a total stranger. But without thinking i run towards him and check if he was ok. The man just stood up (looked like he was in pain) and left without any damages.
Well i dont think this dream has to do with my father’s restaurand. The place i was didn’t caught my attention I only cared about the man.
Thank you.
