I was taking a walk recently, and I saw something that prompted me to do a reality check. I quickly determined I wasn't dreaming, and then a cold wind kicked up a little bit. This made me think about the temperature in dreams, which I had never even considered before. Thinking back, it seems like all of my dreams, lucid and non-lucid, pretty much "happen" at "room temperature." As anyone ever experienced hot or cold in a dream, or to take it a step further, been able to control the temperature?
