Also I feel like maybe it would be helpful to tell the story of the dream that marked the beginning of this problem:

I awoke in my room, it was a false awakening but it was light and I could see everything in detail in my room, as it was in real life. In the lying position, I had a strange thought: what if, when I sit up, my mind can't think of how to fill in the room? So I sat up and it was quite difficult. My body felt heavy but not as bad as nowadays. As I look around the room, I notice that the spots of the room that were missing when I was lying down now are simply spaces filled with materials... like jean and other prints. It was like my mind literally patched up the room. After that, the heavy body thing turned into paralysis.

Thoughts?
