If a woman who is not of child bearing age dreams of a pregnancy, then it is bad. It means she is at risk of engaging in unsuitable sexual acts.

If a woman who is of childbearing age and ability dreams of a pregnancy, then it is most likely that she is pregnant.

If a man dreams of a pregnancy, then it means he is creating a new thing/ project.

Sometimes, men and women who are not child bearing, may dream of pregnancy, because it means they are carrying a new and precious incubation. This is usually a work-in-progress.
