Have you ever gotten so close in your SP stage where its the transformation from reality to lucidity?

You can feel your body sinking into your bed?

But then all the sudden you awaken out of it with no lucidity?

Well i think i figured out what has stopped me a couple of times from attaining lucidity.

Here it is:

When you feel those vibrations and you feel yourself sinking into a dream, your breathing seems to stop. What causes this awakening is the realization of how i couldn't breath, i took a longer deeper breath and found myself awakened with no lucidity.

Instead of taking that breath i should have focused more on being in a dream. By taking that breath i was hanging on to the reality, so my advice is don't take that reality breath LET YOURSELF GO!

Have good dreams everyone! I hope i helped.
