I found this pretty cool what i saw this morning in a lucid dream, but i woke up too soon to know if my suspicions are correct. I became lucid in a dream i had earlier this morning and at some point thought “i dont want to be in this kind of environment”. Almost instantly everything went white. I thought about what new environment i wanted and the first thing that came to my mind was a castle-type setting (i dunno why but i didnt wanna end the dream because of my indecisiveness). After a few seconds of asking for this i saw lines forming. Then some lines connected and came together. Sadly I couldnt determine what the lines were forming because the phone rang in my room and startled me awake. 
I believe i saw a new dream environment begin to form before my dream eyes, but im not really 100% sure. I just felt this was kinda cool and wanted to share to see what peoples opinions were on this. Thats all really 
you are lucky that you managed to form a new environment in this way, I have to close my eyes or teleport to succeed 
Yeah, that would have turned in a new environment. And yes GHOSTIE11, it’s quite hard to make a new environment - in fact it’s very hard for me. So yeah AFanaticNewb, lucky you
haha i suppose it would be lucky if the damn phone didnt ring >.< it wouldve been awsome. But anyways thanks both of you for confirming my belief. 
Next time i become lucid ill try doing this again and see what happens. But thing is all i did was say i didnt wanna be in that dream environment. The last thing i expected to see was white. So i wonder how i can bring about this again
