Birth in a dream usually represents the beginning of something new. This could be the beginning of a new project or a new relationship, the development of a new attitude, or the start of a new lifestyle.
A dream of a birth is often associated with the ending of something, because birth complements death. A dream about a birth can be a promise that an ending or a loss will be followed by a new beginning.
A difficult birth is a sign that it is going to be hard to get your new project off to a good start or to adapt to the changes in your life, but that things will eventually turn out well.
If you are pregnant or in a relationship with someone who is pregnant, or if you are trying to have a baby, then a dream about birth will reflect your real thoughts and concerns about pregnancy.
