When the air planes flew off the ground and reached a certain height, in a cabin that was not so bright. Suddenly I felt that it was time for me to immerse myself, just like lying in the bed and thinking alone in a quiet night. I didn’t know why I got the feeling that the further I was away from the ground, the closer I was to my died grandpa. When I calmed down to think, it seems that grandpa was talking to me and he gave me the answer I wanted in my heart to resolve my feeling of lonely and gave me a certain sense of identity. Maybe I was just talking with myself and just wanted to get the answer, but this emotional feeling is real, which is difficult for me to distinguish.
