Sometimes dreams can represent you subconscious fears. Maybe your mind is trying to tell you that there is something off about that place. If i were you, i wouldn't walk that way anymore. I would go down a couple blocks. Also, the next time the dream comes you should try and use your shoes to dig into the guys hips. Trust me, that will hurt enough to stop anyone from wanting to get back up. No reason to over react to it because it is just a dream, but be careful.
