That's not a bad plan. But you should not be trying too hard.

When you envision the room with chalkboard, that's a good way to start the dreaming process. Just don't be surprised, if some other images start forming. Don't try to controll it, just observe passively.

Don't forget, you need to fall asleep in order to dream.

What I do is just trying to fall asleep, while I repeat my mantra. That should keep my mind awake, until I start seeing images, or have some sensations, or I just get the feeling that I'm dreaming. You don't always get the images or sensations, and you still enter a dream.
