Dreams that could mean something?

Ever had weird dreams? Usually dreams would be forgotten once woken up. However I had this dream which seems to stick on after a few days. I have been pondering if it meant something. In the dream, I am approaching someone, who seems to be demanding something or couldn't get his wish. He then threw something at the direction of my leg. That something seems to be kind of sharp. Somehow I do not feel anything emotion and I just move on away. Once I woke up, I kind of rewind, does that mean I will have leg problem? Meaning my mobility could be affected? Scary but I will be careful for now.
