You can think about it and talk to your significant other about it. I'm having very vivid dreams since becoming pregnant. Yes, it is very normal. Many pregnant women have many dreams about what their child will look like. I had a dream that my child would play hockey.
People have dreams about giving birth to babies that can walk and talk.
Dreams about being inadequate are normal, too. Women dream that they can't find their baby or lose a baby in a store. Many women enjoy sex more when they are pregnant. My husband has four children from a previous marriage. Ninety percent of couples will get pregnant in the first year of trying.
