Now that is interesting :). Because 4am is a very uplifting time for me; it's a time where, if I reach it, I feel very peaceful, very at home in the world, and the quiet makes me feel as if I suddenly understand my place and position in life. In addition, 4/5am are the hours where I get my best ideas, if I can bear to stay up until that time.

But it's interesting it should be so dark for others, and another reminder of how we don't all work on the same frequency.
