What does it mean when you have a dream about having a baby with someone you have NEVER talked to in your life?

I'm not very into the "dream meaning" of it all, but let me explain dreams in a biological way.

The brain is a road map. Everything you see, everything you hear, every thought/feeling you've had, rests in your brain, but it's not a linear relationship. It's recorded in convolutions, but dreams are linear. So imagine, a very windy road, which is your life experiences, and your dream is just going straight through the windy road, cutting through everything.

Example: You met a guy named Tom. You also met a cowboy. You went to an ice skating rink with a friend.

Your dream could be: Tom wearing cowboy clothing while ice skating.

So when you have a dream like that, it could mean that you've seen a show/talked to someone about a baby, and that person just happened to enter it.
