When the weather is cold, you will have nightmares as long as your body is exposed. How's it going?

What nightmare did you have? When you sleep, the activity state of your body will be brought to your dreams. For example, if you are in a hurry, you will always look for the toilet in your dreams until you wake up. Because your posture is wrong and your heart is crushed, you will always have nightmares. When it's cold, the body will definitely freeze when exposed, because it's uncomfortable to be cold and it's normal to have nightmares. When you wake up, you will be covered with a quilt, which is also a kind of protection for your body, otherwise it will be easy to get frostbite if you don't freeze overnight.
