In The Phase guidebook, there is also a section about the Forced Falling Asleep (FFA) technique which can be used in conjunction with the indirect method and is extremely effective. To check this out go to page 230 (FFA - Maximum Effect). This can bring your odds of success near to 100%!
To quote from The Phase - A Practical Guidebook:
"Forced falling asleep, to put it simply, is a way to reel that receding lifeline to the phase back towards you. It tricks the brain, which will react automatically to all your actions and quickly thrust you into an intermediate state that is easy to use to enter the phase."
