The dream probably uses the image of pregnancy as a metaphor representing something you and your girlfriend are "gestating" or developing together. The dream suggests that she may not be as willing as you assume. On the other hand, the dream could be a nudge for you to be careful and use appropriate precautions when having sex.
im not a mind reader but if i was to make a guess i would say that you are afraid to get your girlfriend pregnant. i had a similer dream. but its nothing to worry about if you do it safley.
Next time use a condom before messing around with your friend's girl.
you might be pregnant!
it means you do not trust your girlfriend.
Assuming that the dreamer does not have horrendous memories of criminal abuse, the pregnant woman in this dream is a metaphor. As such, the dream could be illustrating the dreamer's fear that an important development might be destroyed in its early stages. Similarly, it might express angry disappointment regarding lost opportunities.
If you dream about having a girlfriend, it does not necessarily mean that your man is straight; it could be due to your fears of finding out that your man is not straight.
your mad at your feet
The dream probably expresses your jealousy or feeling of being inadequate to hold the girlfriend's interest.
It more than likely doesn't mean anything; a dream is just a dream. Don't hold your girlfriend accountable for something you dreamed happened.
The dream expresses your own desires and emotions. It does not predict the future and it does not reveal your girlfriend's thoughts or feelings.
that you dont like his girlfriend
This dream illustrates your own feelings about your girlfriend rather than revealing her behavior or intensions. You might suspect that she is cheating, and the dream reveals your suspicions. That does not mean that she is cheating.
