Why do I sometimes wake up in the afternoon and feel like I’ve been in another world?

We have all had such an experience. When we wake up in the afternoon, we feel as if we are in a distant world and don’t know why. It is what the saying goes: sleepiness. But the strange thing is that we don’t feel this way when we go to bed late. How can there be such a big difference when sleeping in the same way? This also starts with the difference between taking a nap in the evening and taking a nap in the afternoon. We generally don’t sleep for too long during the afternoon nap, unless we are extremely tired or have nothing to do before we can have a peaceful sleep. But it wasn’t too long, but because we slept relatively deeply, it felt like we slept for a long time. Once again, I slept from noon until the afternoon. When I got up, I saw the darkness outside and thought I had slept until the morning. At that time, my mind was groggy and I wanted to go out to buy something for breakfast. After walking for a while, I found that there was no one selling breakfast. My mind became clearer, and I realized that it was just evening. I was so sleepy that I couldn't even tell the time.

It is often difficult to fall asleep at noon, and it is often necessary to toss and turn in bed before falling asleep. Moreover, as soon as I fall asleep, I fall into a deep sleep and sometimes have a big dream. Suddenly I wake up and I am still immersed in the dream. I feel that everything in the world is illusion and only the things in the dream are real. It is said that Zhuang Zhou dreamed of butterflies, and butterflies dreamed of Zhuang Zhou. It is precisely because of this that we feel as if we are in another world, but this feeling of being in another world slowly disappears when we wake up. To put it bluntly, the most important reason why waking up from a nap feels like a world away is that we haven’t slept enough. If you go to bed at night and sleep until dawn, instead of feeling as if you were in a different world after waking up, you will feel refreshed and energetic.
