Pregnancy dreams?

Alright ladies. I need to advice. My husband and I have been ttc for about 3 years. Lately I’ve been having very detailed dreams that I am pregnant. This has happened almost every night this week and I don’t speak or think about pregnancy often. My grandmother even had a dream on Christmas Day that I was pregnant. However, I’m not, and everyone test I have taken is negative right away and same for blood tests done by my dr. I actually am on my period. Has anyone ever had those dreams and they actually come true? What does this mean?? It would be a miracle for us.. I was on depo from age 16-19&1/2. But, I can’t seem to get pregnant this time. Most people say depo leaves your body after 2 years but I still haven’t gotten pregnant. It took over a year to have a period again and when I got it it was the worst of my life and still are. They’re heavy and I have cramps that feel like contractions and a miscarriage all over again. They became regular and started becoming irregular again recently and I just got it after missing 2 months. I’m scared depo screwed me up and I’ll never have my baby.. but really, why these vivid dreams?? It gets my hopes up and breaks my heart because I wake up knowing it isn’t true! Any and all advice I can get would be so appreciated
