Is this a comment or a question? Dreams can have hidden meanings or are their to entertain, it depends on the frequency and vividness.
There's a couple methods I've heard about to have the same dream [though its never worked for me] the simplest would be meditating while thinking about the dream, it should take you back to that point, but this take practice. Food or scent can be used to remember a dream as well as influence. Telling yourself to have the dream again apparently works too. Either way, keep a journal handy as you loose 95% of your dream after the first couple minute of waking.
What you were most likely dreaming of was a handfastening [wiccan/witches wedding] so either look up what a wedding means in dream interpretation, or research handfastening ceremonies to hopefully find the chant, or similar.
