Dreaming of twin babys

Z • Ftm due Jan 10,19 with a baby boy💙
Hello ladies, 2 days ago I had a dream I was announcing I was expecting twin babys and I was so excited. I told my SO and he said " Really because I had a dream you were pregnant" the same night I had the dream. That's the first time he dreams about me being pregnant. Today I had another dream, I was holding the baby. What can this mean? Is it a sign? I used pre-seed last week. Let's see if it worked. Thanks in advanced and Baby dust to you all. God bless.
