Dreams are about the dreamer. So a dream of one's sister being pregnant contains information about the dreamer, not the sister. More importantly, dreams about being pregnant and/or having a baby almost always are metaphors for some project or new task that needs to be developed and brought to completion in your life. So unless the dreamer has been sexually active (in which case a pregnancy test is in order) the dream is probably about a new phase of life or perhaps a fresh assignment coming your way.
The dream refers to something that is developing in your life, or in your family, that is connected in some way with your deceased sister. There might be some unexpected development in the settlement of her estate, or some family history may have come to light only after your sister's death.
The deceased sister in the dream represents your self. The pregnancy is a metaphor for something that you thought was dead within you that is suddenly showing signs of life. For example, the pregnancy might represent the love for music you had in the past or even a relationship that you thought was beyond restoration.
The most likely meaning is that, in the dream, your sister represents yourself. The pregnancy represents something very important that you are struggling to develop - it might be anything from a big idea to an important project or task. The idea of "heavily pregnant" suggests that this project has become very "heavy" in the sense that it is weighing you down and has become the center of your life, but that the completion is within sight.
It means that you ae going to get pregnant soon if your sister dreams of you being pregnant.
Dreams do not have to mean 'anything'. You could think of dreams as your brain venting to prevent it from overloading.
Pregnancy dreams are usually about change, specifically anticipating change.
it means you need better dreams and that you want to emmbarass your sister
Dreams are about the dreamer's own feelings and thoughts. In this dream, the sister-in-law could represent the dreamer, and her own suppressed desires and fears about becoming pregnant. Alternatively, the "pregnancy" and "baby" might symbolize some idea, project or task the dreamer or the dreamer's family has undertaken, and the dreamer's fears that the project will fail.
Dreams are about the dreamer. So if another person dreamed that you were pregnant, in the dream "you" represent something about the dreamer herself.
Dreams are always about the person who has the dream. So this dream has something to do with your sister's own need or desire to have a family, or perhaps her need to nurture some male aspect of her life.
It is possible that your husband has noticed, subconsciously, certain hints and signs that his sister is "developing" something special. This could be a pregnancy but it could also refer symbolically to a project or idea that is important to her. However, dreams are about the dreamer, so it is more likely that the dream refers to something "developing" in your husband's own life. His sister in the dream could symbolize his own feminine, creative side that is ready to become productive.
Usually nothing. It could just be them wanting you to be pregnant, or just a freak thing. My mother dreams of me being pregnant quite frequently but I am no where near ready for a child right now.
It means that you're thinking about pregnancy. Dreams have no external sources.
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.
In dreams, a person of the same gender as the dreamer usually represents the dreamer's self. This dream suggests that the dreamer is struggling to bring some idea or project to completion.
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.
That you need to feel like someone cares about you
