Repetitive dreams/pregnancy

My husband had a vasectomy August 20th but hasn’t been cleared yet. We stopped using protection beginning of October not thinking anything of it. I’m still breastfeeding our 9.5-10 month old son and still haven’t had a period since before I got pregnant with him.

I have been having the same dream for the last 2-3 weeks. No clue why or what brought it on. It’s got me curious wondering why and what it means though.

The dream is me pregnant with twins. I took a pregnancy test yesterday (November 6th) and it came back negative. Anyone ever had repetitive dreams that were true or had meaning in reality? Ever got pregnant while breastfeeding and soon after S/O has a vasectomy?
