If you have dreams of preg woman that mean?

Well that could mean a multiple of things

If you are a woman, it could mean that you're pregnant

or for either genders, it could mean you want to get pregnant, know someone who is pregnant,

or you just have a fetish for pregnant women in your dreams... (just kidding)

My advice,

Get to know your woman friends better, talk to them and see if they're thinking about having a baby...

and if you are a woman and have had sex recently, go and get tested... that could be a very big sign of pregnancy....
