How to create dreamy looking photographs?

Hey I'm an amateur /begginer/ photographer and I've been looking through a lot of photographs to decide which style suits me best. I really like the work of Tyler Shields, but I much prefer "dreamy" and "soft" looking photos like those of Alexandra Sophie http://www.alexandra-sophie.com/, Anastasia Volkova.
P.S. If you know any other photograohers with similar style, please mention.
Also if you know the name of this style?
But my main question is, how can I create these soft, dreamy photographs? I have a Nikon d5100 with a 18-105mm lens.

I can't help you a lot but I know some sites that may help you.
