Well, it finally happened. After one long year of research and practice, I had my first full-length LD. It was spectacular. I randomly did the nose-plug RC, and like magic, it just happened. 
I just have one question:
How do you go about creating certain objects in the dream world?
I was able to create small things, (like a specific amount of quarters) and create copies of a friend of mine. But bigger objects, (like a car) were challenges for me, and I couldn’t do it. Any suggestions?
The dream was from low-somewhat low lucidity. Not sure If that means anything. 
Thanks in advance!

what i like to do if i wanted a car is i turn around and i say firmly, “There is a car behind me!” and alot of the times a car is there. Another thing you can do is ask a DC and ask like “hey wheres my car?” and its likely theyll tell you exactly where a car is 
But congrats on your LD!!! 
Um, small suggestion: Try finding a dream-guide in your LDs. You can even pick a random DC for it. Ask them all what you have to do in order to spawn objects or even create your own world. 
Similar to what Limitles said, you can also turn around a corner or walk through a door and expect the object to be around the corner or behind the door. Works well for finding persons, too
