I have thought about DILD'ing. Though, I'm not too confident that I will be able to wake up during the night, I can't really wake up with an alarm clock. If it does happen, though, I will make sure to attempt it

Is it guaranteed that if I lay still for long enough I will achieve SP, though? Once I was extremely tired and I didn't want to fall asleep so, when I was going to fall asleep, I kept opening my eyes to wake up. One time, though, I waited too long to open them, and I was in a Lucid Dream!
