Do dreams actually mean something?

My husband and I have been ttc for a couple of years without luck. Our first and only pregnancy ended in mc at 10 weeks in 2016. As of January this year we have taken a break from the charting, temping and opk testing. Many have told me they finally got pregnant after they "stopped trying." That hasn't happened yet either. I've actually kind of given up on the thought of it until today. My mother told me that her co-worker (that just had a baby) has dreamt twice of me being pregnant with twins. Then I realized that the entire month my boss keeps picking on me about being pregnant. Neither one of them know that a baby is actually a deep desire of ours. Do you think this could be a "sign?" I know I've let people in my head but I'm curious to know if any of you have had an experience similar? Thanks!
