Strange night

Guys, we all sometime, spend a sleepless night. I had mine, last night. So I stood at my window and found some strange things.
1) why is that dogs barks in a melodious way!
2) breeze ride when u least expect.
3) you never find anyone, standing at her/his window and thinking exactly opposite that, wht you are thinking.
4) (this is my fav) why is that, when you open your refrigerator you find nothing worth to eat.
At the end, you fall asleep and cannot remember how!
