I totally agree. I feel much more energized when it's cloudy and rainy outside. I like it sunny on cold, crisp autumn days though.I don't like heat...it kills me, makes me slow and lazy. All I think about is sitting in a tub of ice. For this reason I hate the summer. I also dislike it when its very bright and sunny outside. I prefer sunset or a night with full moon.
Bright sunny days feel very gray and lethargic to me.
