Intent

"He who calls on me by whatever name, is mine, and dear to me." Same goes for whatever method one chooses. It's the intent that matters, not the method.

Ego Is Secondary

A healthy ego knows it is not the top dog, it's just a tool to navigate the relative world. An ego that acknowledges it's secondary status to the Self, God, the Absolute, is helpful, not harmful.

Relative World and Ignorance

If you are the Absolute and know it, then of course there is nothing to wake up from. But, the whole reason there is even a term "enlightenment" is because we live in ignorance of our true Self.

Any normal human being does have something to wake up from, assuming he realizes his ignorance. Dream or not, there is a relative world, and our human selves live in it. We can play the game in ignorance (nothing to wake up from), or we can get off our butt and try to get to the truth.
