Could a mantra handle this?

[Saurfang]

Hey guys, I have already expierenced the power of mantras. Once I used this mantra: "I will wake up after my first dream" and in my first attempt, I woke up directly after a dream at 4:00. That was amazing. Tonight I want to try this mantra: "I will wake up in 5 hours" Do you think this will work? Waking up at 5:00 would really increase my chances of having an LD, however if mantras are not powerful enough to make me wake up in a specific amount of time, I could use some ordinary mantra like "I will have a lucid dream" "I will do a reality check" etc. etc. etc. So, what are your thoughts on this? EDIT: To avoid posting multiple threads, I wanted to ask this little question about WILD: Is focusing on my breathing good idea to push my mind away from daily thoughts? Will loud breathing through my mouth not affect WILD negatively? I mean won't it make SP harder to achieve etc.?
