Dreams are about the dreamer, so it is very unlikely that one would receive information about someone else's pregnancy in a dream. It might reflect the dreamer's feelings for that "someone," that they are "full" of ideas or creativity or that they are literally or figuratively "fertile." Alternatively, the "someone" could represent the dreamer, so if the dreamer is a sexually active female of childbearing age, a pregnancy test would not be a bad idea.
Another Answer:You may have anxiety about things you have done. Unresolved issues. In the dream, are you being accused of something? Or is the person simply a friend of yours? It is very different when your girlfriend tells you she is pregnant than when a coworker confides in you, or your mother happens to mention it...Dreams are hard to interpret even when they seem very clear. Often I suspect there is no real interpretation. One useful technique for extracting meaning from dreams is to assume that each character in the dream is you, or represents some part of your own psyche.
This dream suggests that some part of your self really does not approve of that person.
That you need to feel like someone cares about you
It's telling you that you're pregnant. I've had dreams similar to that.
You or someone else that you know are thinking that they are pregnant and they want to know if its true.
Each dream is about the dreamer. In any other person's dream, "you" are an image that represents the dreamer in some way. So if someone dreams that you are pregnant, that dream reflects something about that dreamer, not about you.
Dreams are about the person having the dream. So this other person's dream is about that person, not you.
you are getting f'd over by elephants that can smell through their feet!
you might be pregnant!
Dreams can mean everything or nothing, they are less controlled than some people would like to think. Your dream possibly means that you are desparate for a baby.
What does it mean if you cant find someone your looking for in your dream
Dreams are about the dreamer, so the "someone" in this dream is yourself. If you are female and have been sexually active since your last menstrual period, a pregnancy test might be a good idea. Otherwise, the pregnancy is a metaphor representing something new that is developing in your life such as an idea, plan, project or commitment.
Dreams are about the dreamer's own thoughts and feelings. When you appear in someone else's dream, "you" generally represent the dreamer's own self. Whether or not that dreamer is pregnant has no particular meaning for you, one way or another.
