Weird dreams after mc?

I know itll prolly sound funny, but I had a dream of how many kids my husband and I were gonna have? In this dream I had a girl that was around 4-6 and a baby boy around a year, my "daughter" ran up to me and asked "mommy when will we have another brother or sister? I know our other one went to heaven" I said "I have a secret im carrying him/her in my tummy" then I woke up! It was weird.... I cant be the only one to have a dream like this!
