To describe a movement like a jab in a dream can represent focusing on, and identifying what you want. Similar to a fork that allows you to take a stab at the idea of nourishment, a jab can be a wake up call to explore what you are not confronting. The character that 'takes a jab at you' might be considered in light of a tendency to be self defeating in some way. An unacknowledged part of you may be stirring and attempting to get your attention.
