I dreamt that I went back in time?

To make a long story short I dreamt that I went back in time 8 years to when I was with my ex husband and I suddenly had all the knowledge of my life until now. So in the dream I left my husband since I knew what a jerk he was. But I kept thinking about my current husband, the love of my life who lived half way across the country so I took a trip to find him and I did and after much persuasion I convinced him I was not crazy and that by listening to me we could have so much more time together and save us both alot of heartache at the hands of others. What do you think this means? Is it frustration that I wasted so much of my life or is it something else? I have never had a dream that was so detailed and involved.
