Dead body - usually represents some area of your life that has 'died'. It can represent the death of feelings such as hopelessness in connection with relationship, and the loss of feelings about someone; the depression that follows big changes in life, such as the loss of a loved one, loss of a job, etc.
Also, a sense of your life in general without the stimulus of motivation and satisfaction...like a feeling of 'going nowhere....or repressed anger killing positive expression.
The dead body may be linking several of these feelings together, because these types of dream symbols often represent large areas of experience. In this way, the dead body represents a part of yourself you want to leave behind,...to die out.

Not able to 'have fun' with this body - suggests your inability to enjoy life in general.

Skin - represents our contact with the world, and those around us....the tactics we use to deal with others; strength or vulnerability in feeling the impact of other people, their remarks, and actions. That the skin is gone, suggests you feel exposed, vulnerable, or without protection.

No arms or legs - usually pertains to the sense of inadequacy, or lack of physical function connected with those limbs. No legs would then be seen as the inability to stand up for your self, or to 'stand your ground'. No arms would relate to the inability to 'reach out' to others, the inability to give and receive, or to 'keep things at a distance', to protect yourself...etc.

Babies head on adult body - symbolizes an approach to life, or an area in your life, in which your thinking is still immature, even though you are physically mature.

Blood all over - It is the life-giving, vital part of our physiology and it may symbolize our strengths and weaknesses and our physical and mental health. If you are currently experiencing a very difficult time in your life, you may have dreams with bloody and frightening images. Don't worry, you may be venting your fears!

Police -  symbolize support, protection, structure, rules, and control. Also, a sense of what is socially right, or wrong. Our feelings of what others would dislike, or would punish us for; our social rules of conduct, rather than our innermost sense of rightness (inhibitions, or feelings of guilt, or shame).

Church - could represent a need for greater spirituality in you life(Not meaning more religion in your life, but a greater sense of self). It may express beliefs, everyday occurrences, issues of safety, security and strength through community and expression. None of us can escape the age-old questions, "Who am I?" and, "What is the meaning of life?". Coping with our own physical mortality is a very big deal. Both our conscious, and subconscious minds are continually working and bringing issues of relevance and concern into our awareness.
Your subconscious may be urging you to "center" yourself, to pull yourself together instead of going in opposite directions.

Happy Funeral - symbolizes a death to old attitudes and/or habits. Putting to rest a part of yourself. You may be burying relationships, conditions or even emotions that you no longer need and that are no longer conducive to your personal growth.  You are finally letting go of something.

No-one noticed the body - suggests you feel 'ineffectual'. That you feel un-noticed, or unappreciated, in your waking life.

Lovely old lady - usually the elderly represent wisdom, experience, and patience. She could be representing the wiser, and more patient, part of yourself.

Felt angry - reflects the fact that anger can be destructive and sometimes ends up being treated as a taboo. The fact that it comes out in dreams may be attributed to the 'self', and the primitive instincts underlying our personalities. People who dream of being angry sometimes have difficulty expressing the emotion constructively in waking life.
Dreams that contain anger may often give insight into our waking relationships. Sometimes, you may find yourself dreaming of being angry at someone who never angers you in waking life. This may simply be an indication that they are not perfect, a sort of check that reminds you that they are human.

Do you feel as though you don't 'make a difference' in the world around you?

Do others tell you you're acting childish, when you become angry, or they don't 'validate' your anger and just ignore it, and you?
Do you feel angry at someone for not accepting you for your ideas, or experience?
Do you feel unsupported in your ideas, or beliefs, by your husband...or friends?
Owning your own business is tough. Have you been feeling that it's too much work, and you'd like to be able to have fun, or to be able to enjoy yourself?
