Me and my mother had the same dream on the same night. I was pregnant and holding my ultrasound photo and I was sure baby was a girl. My mother told me she also had the same dream that night that she saw an ultrasound photo of a baby and she also saw the baby (didn’t know gender) I am not pregnant but plan to be in the future. What could this mean? Both to dream the same thing? 

Because dreams are expressions of the dreamer's (yours and your mom's) feelings abt what's going on in their life, having the same dream as your mom at the same time suggests that you both feel the same about the same thing... in this case, something that is "growing" inside you.  Here are links to the dream dictionary definitions on this site that should help you connect the dots between your dreams and your respective lives...

Hope that helps.

From what I have read, two people having an identical dream is uncommon.

Let me know when the baby arrives. It will. The dreams are Precognitive. But be patient. It may be soon or maybe not. Only our Divine Creator knows when the babe will arrive. Good Luck.
