"I'm Being Chased"
Chase dreams is one of several common dream themes. As with most of the common dreams, they often stem from feelings of anxiety in your walking life. Running is an instinctive response to physical threats in your environment. In these dreams, you can be pursued by an attacker, an animal or an unknown figure, who wants to hurt or possibly kill you. In turn, you run, hide or try to outwit your pursuer. Your actions in the dream parallel how you respond to pressure and cope with fears, stress or various situations in your waking life. Instead of confronting the situation, you are running away and avoiding it. Ask yourself who is the one chasing you so that you can gain understanding and insight on the source of your fears and anxieties.
The pursuer or attacker who is chasing you in your dream may also represent an aspect of yourself. Your own feelings of anger, jealousy, fear, and possibly love, can assume the appearance of threatening figure. The shadowy figure can also symbolize rejected characteristics of your self. You may be projecting these feelings onto the unknown chaser.
If you are the one doing the chasing, then the dream may highlight your drive and ambition to go after something you want. Or perhaps the dream suggests that you are falling behind and having to catch up with everyone else.
Consider the distance or gap between you and your pursuer. This indicates your closeness to the issue. If the pursuer is gaining on you, then it suggests that the problem is not going to go away. The problem will surround you until you confront and address it. However, if you are able to widen the gap between your pursuer, then the problem is becoming less and less of an issue. You are able to successful distance yourself from the problem. In essence, the problem is fading away.
A more direct analysis of chase dreams is the fear of being attacked. Such dreams are more common among women than men, who may feel physically vulnerable in the urban environment. These dreams are inspired by fears of violence and sexual assault in which we are so over-exposed from the media, which magnifies such fears.
