To dream that you are born again, indicates that you need to deal with issues that you have been avoiding. You may have been given a second chance to regain what was previously thought to be lost. Alternatively, you are starting or entering a new stage in your life. You are looking toward the future without dwelling on the past.
Some Christians are described as "born again". Thus the dream may also represent your renewed religious faith and commitment.
A new beginning, a new creation, the start of something new, or a new phase in life, relationship, career, etc.
