Empty White Room Dream: Meaning of Emotional Meaning & Interpretation

"I woke up in a white room. There was nothing in it. No windows. No doors. No furniture. Just white walls. I stood up. The floor was cold and smooth. I walked to the wall. I touched it. It was solid. I walked around the room. Every wall looked the same. There was no way out. But I felt nothing. I was not scared. I was not sad. I was not happy. I just sat on the floor. I looked at the white walls. I felt empty. Like the room. No feelings at all. I sat there for a long time. I did not move. I did not think about anything. I just existed. The room was quiet. Completely silent. I closed my eyes. I felt nothing. When I opened them, I was in my bed. I sat up. I felt normal again. But for a moment, I felt strange. I could not remember why I felt so empty. I shrugged and got ready for my day."
