Hey Brucely
All dream symbology is a refection of our own internal landscape that is they represent our, feelings, emotions and behaviour in some way shape or form.
Police often represents some masculine authority, often beliefs or thoughts and attitudes that could assist you in life, if you allow them. Running from them indicates that you are not currently able to “ask for or receive higher help”. In dreams they often serve as guides that can offer you assistance in some way.
Females in dreams often represent feelings or emotions, being held by the store owner may show you how you are being held by some emotion and the internal battle that ensues. To run away is to run away from this feeling or emotion that causes you to panick.
Cars often are a comment on our daily life and your friend seems to represent some attitude or behaviour that takes you away from this place or allows you to escape when you find yourself captive by uncomfortable feelings. If you reflect on your daily life you may be able to pinpoint emotional situations that cause you to panick and feel uncomfortable. What is your attitude and behaviour when you find yourself in these situations?
The ambulance here seems to indicate some form of healing is available and the police as already mentioned indicate beliefs or thoughts and attitudes that could assist you in some way when you encounter this internal landscape in self rather than being 'driven' by a familiar attitude or behaviour that has assisted you in the past to deal with uncomfortable situations. As a result when you do encounter uncomfortable emotions the flight response you have takes you into an unconscious place 'the forest' and you lose your awareness around the situation.
This scenario will keep replaying in your life until you make what ever it is that panicks you conscious. Understanding and bringing to awareness our emotional self is key in addressing why we act the way we do. Our emotions often govern our attitudes and behaviour.
Keeping a journal may assist you in some way to reflect on your current personal life writing down how you feel in your day to day situations and events that you encounter may help you to shed more light on your dream.
These are just some ideas to your dreams meaning. Good Luck with it all
