Hi! to dv.

You can definitely change your dream scene. For me it's really hard. But for others it's really easy.

Try going through a door and imagining the dream you want to be in on the other side. When you open the door the dream will be right in front of you.

What I do is use DEILD to change my dream scene. If I'm lucid and want to go somewhere else then I will wake myself up and go into a different dream.

If you would like to find out how to DEILD use this technique. Dakotahnok's DEILD tutorial.
