I was also bored. Maybe these will help you figure out what your cow dream means
Cow: The eternal feminine, especially the mother or mother figure, is often depicted by the cow. This is partly because it provides milk and nourishment.
Animal with a cub: This will represent motherly qualities and therefore the mother.
Baby animal: The dreamer will be dealing with the child-like side of his or her personality, or possibly children known to him.
Deformed animals: Through such a dream the dreamer realises that some of his impulses are offensive or revolting.
Sinister animals: Any threat from animals indicates the fears and doubts the dreamer has over his ability to cope with the stirrings of the unconscious.
Bite: Being bitten in a dream may show that we are experiencing aggression from someone else, or conversely that our own aggressive instincts are not under control.
Limbs: In dreams any limb can be taken to mean sexuality and fears associated with gender issues. Being dismembered can be taken in its literal sense - we are being torn apart. Sometimes this can suggest the need to restructure our lives and begin again. At other times it can indicate that there is a way in which we are being threatened to the very core of our existence.
Field: When we dream that we are in a field we are looking more at our field of activity, that is, what we are doing in everyday life. It may also be a play on words in that it is to do with the feeling state and is to do with the freedom from social pressure. It may also be an indication that we need to get back to nature, to basics as it were.
Friend: A friend appearing in our dreams can signify one of two things. Firstly we need to look at our friendship with that particular person, and secondly we need to decide what that friend represents for us (for instance: security, support, and love). Often friends highlight a particular part of our own personality that we need to look at, and perhaps understand or come to terms with, in a different way.
