land where nothing was past

When I died last week I went to a land where nothing was past. Because all people there remembered every single thing about everything past present and future. They were all laid down on their couches. Staring at the stars overhead with eyes that looked dead. Some explained to me this was an illusion of my mind. I was too used to see only the present time. They were actually floating at various speeds at all the dimensions that they wanted to be all at once. I came back from my death with a smile on my face. The nurse told me I was singing in the middle of my anaesthetic stupor. Neither of us could identify the song.
