Those who slept on the train, tell me how they feel.

I put my bag under my pillow to get ready for bed. I was confused for a while. At the station, someone got off and someone got on. The people who got on the bus were too excited to sleep, thinking ~ ~ finally confused again, and then got on and off again ~ ~

In short, sleep is unstable, sleep is not practical. The strong feeling that "sleeping at home is still very comfortable"
