Good post about fearlessness , Leo

I'll give you a slightly different perspective - your subconscious mind attempting to interrupt or prevent your lucidity is a side effect of inexperience. While I was still new to the whole lucid dreaming thingie, my mind constantly tried to trick me out of lucidity. Voices during WILD, sometimes catastrophic failures or attacks by unknown entities all ruined my lucidity and made me wake up.

However, after I mastered certain degree of dream control and awareness, the attacks/voices/failures completely stopped.
