Perhaps a significant change in your life is coming up
maybe that's how you feel right now, but feelings can and do change, especially if the right person comes along; and dreams about giving birth could also signify you giving way to some creative outlet; a new you being re-born.
Dreams ALWAYS have a symbolic meaning....kids dreams means you're becoming new, developing new sides to your personality, or a full new personality, youre getting past trauma etc...
The characteristics are a symbol, like if he's tall, it means you're getting more stature, more importance, and respect in society, fat, you'll getting abundance, money....etc
It could mean many things, depending upon your life's circumstances. Pregnancy in dreams doesn't always relate just to having children. It could also be related to some aspiration you have regarding your school-work or career, or some other project that you're working on that you hope will work out very well for you.
Do you have any big class projects, or some kind of performance that you're preparing for right now?
Was last semester your first at college, have you recently switched majors, have you started thinking about graduate school?
There it is. The pregnancy symbolizes the (very natural) anxiety that you're feeling about the process of finishing high-school and applying to colleges. That's a perfectly normal dream for a woman your age to have.
DEEP DOWN.. YOU DO WANT KIDS. ADMIT IT.
