Dreams about pregnancy have many different meanings. For example, a person dreaming about someone else being pregnant sometimes means they are suddenly feeling a closer connection to that person. However, it could also mean that the dreamer feels that the other person has something inside needing to be let out or something they need to finish.
In some cases, a dream about another person being pregnant actually turns out to be true and the person really is pregnant.
If a person dreams that their partner is pregnant, it can mean one of several different things, depending on the context of the dream. For instance, if the pregnancy is seen as a good thing in the dream, it can be a sign of wanting to move forward and settle down with the person or of wanting to fulfill the wish of having a baby. However, if it's seen negatively in the dream, it could indicate a fear of responsibility.
When someone's partner dreams that they are pregnant with someone else's child, the interpretation may be a bit more worrying, as it often indicates that the dreamer feels the couple is drifting apart or that their partner is moving in a different direction than they are.
