Late Night/Early Morning Thoughts

When i'm half asleep I always tend to think more clearly, if that makes any sense. During the day I have so many things on my mind and distractions at hand that it is hard to focus. But as of right now (when I should be sleeping) I am half asleep. Therefore I feel like I have a better attention span to think things through. I am able to cut to the chase and not over-analyze my work or topic. Maybe that's why I tend to my work late at night/early morning? When it's quiet and I have less distractions...but I feel like this isn't healthy. This whole thing is just plain weird to me.
