Pregnancy dreams

I wouldn’t exactly call this a confession or secret, since most of family knows about it, but I don’t know anyone else who has them. For the past decade, I have been having dreams where I am pregnant. Sometimes it includes everything from the conception to a little bit after the birth. Most of the time I don’t know who the father is. It’s like a black cutout. Once it was a history teacher I had at the moment (I could not look him in the eye for months afterwards). I’m 24 now and I feel like they are never going to stop. For the most part, I seem happy in the dreams, but I can’t shake the question of why they keep happening. Most online articles describe it as a sign that something is changing in one’s life, but it doesn’t really match me. I’ve been pregnant approximately 40 times now in these dreams. They are also my most memorable dreams. Does anyone else experience this? If so, could you detail some of them. I’d be happy to divulge more specifics to compare! Thanks!
