I read somewhere that a pregnant woman's dreams about whether she's having a boy or girl are typically more accurate than chance (I don't remember where I read that, probably somewhere stupid, to be honest).
For the last month or so, I've been solidly convinced I'm having a girl. Initially I was sure it was a girl, then I thought boy, and when I first went back to girl, I thought, ok, now you're being silly. But I've thought girl for a long time now, long enough to say it out loud.
Then, two nights ago, I had my second dream that I had a boy. So now I'm questioning that again. I mean, that's twice now.
On the other hand, the same night, I had a dream that someone was trying to kill me so they could eat me, so maybe my dreams aren't telling me much about reality.
