Quote :dream control isn't something you get with practice, its a state of mind.

You're right about that, but what you have to practice is having a clear mind when you go to sleep,any problems, toughts of the past day (unless it's your focus) still floating in your mind will be a part of your failure.
If you can relax yourself to the point treshold when images starts to flash and you hear bits of sounds of the actual dream without any toughts in your mind, and still be awake (lucid) it's almost certain that you'll acheive it.
So yeah, state of mind is right .

Edit: maybe it's just me but i find that it happends more often in the afternoon for those lucky enough to be able to nap during the day
