If you read many authors on OBE, you will find that all of them at one point or another change the way they project- Monroe is the first one I can think of- he went from going through the 'usual' vibrations, 'reaching out' to project, and 'old fashioned' RTZ OBE to directly phasing into the astral. IIRC so did Moen, and many others have gone through some change after they had established a specific method of preference and gotten some experience.
Many of us, at some point or another, find that all of a sudden they are not getting the same symptoms, or when they do exit the 'usual' way they don't end up in their room, or they bilocate, or they have dreams in their room, and they also find that their dreams become either precognitive or significant (in that they experience stuff that is happening somewhere else or in someone else's head) and other 'shared dreaming' type of experience.
As you practice and project and cultivate conscious exploring, you are changing how your mind works, and how your energy body works too, and thus at some point you find that things change, slow down or become dramatic- and this tells me that you are evolving as you practice- so that your experience evolves too.
That's why I suggested you deepen your meditations without the expectation of projecting- it'll develop your clair (voyance, audience, or whatever your natural predisposition is) and then you can decide what to do next.
I just don't know why I think like that. I'm not sure I get what you mean by this.
