dream fragment

Walking through an ally with a couple other people.
A man with long black hair dress with a long black coat and chains appears in front of us a few few yards away.
Suddenly he attacks. The person beside me gets hit and a second later I too get get hit.
I fall to the ground. sand covers my face. I manage to roll out to the side.
I see the chain with some sort of blade is stuck in my shoulder. I pull it out.
A moment later the man walks up to one of the people I was with, who is uninjured.
The man turns, looks at me and say "you may not yet take this path".
