A dream featuring a pregnant woman — yourself or someone else, and not functioning as a literal taemong about a real coming child — is generally read through the idea of something growing that isn't ready to be revealed yet: a plan, a project, or an ambition that's real and developing, but still private.
Seeing a stranger who's visibly pregnant is read as news of new beginnings somewhere in your wider circle — not necessarily involving you directly, more an awareness that something is developing nearby. A pregnant woman who seems calm and content is read favorably, as steady, healthy progress on whatever the dream represents.
A pregnant woman who appears to be struggling or in visible discomfort is read as stress connected to something not-yet-finished — a plan that's further along than you might admit, but genuinely difficult to carry right now. Watching someone give birth within the dream, separate from the taemong tradition's specific symbol-receiving moment, is read as a project or long effort finally reaching completion.
Because this dream sits so close to the taemong tradition without quite being it, it's worth checking the dedicated taemong article on this site if the dream involved a specific, memorable symbol (an animal, fruit, or jewel) — that's the more precise reading if a real pregnancy is actually involved.
