Well I for one like to believe that dreams are connected with some aspect of the mind and spirit and it usually gets to you in ways you understand Like for me my dreams or those I remember are usually sexual If I miss a girl I see her in a dream when I’m hanging out with new girls I’m seeing When I’m stressed about something it’s usually something haunting me And in your case it’s a pregnancy, pregnancies imply a weight to carry but a blessing after birth And the birth won’t be easy either So my answer to your dream would be something heavy you are carrying and might be a burden or a weight in your life So it’s either a good load you are carrying( like a baby or a blessing) or it’s stress that’s building up and you are carrying it I’d say the reason you saw yourself pregnant is likely because there might be some relief to be found from unloading the weight I think this is it
