Spoiler Thread: Avengers Infinity War

I always felt that the Thanos we saw at the end of the film wasn't the "actual" Thanos. I felt that the idea that he would "sit and watch the sun rise over a grateful universe" was not literal. That would be too damn cheesy it seems and not very "Russo". He took way too much damage to his body to walk away unscathed like that, even with the Infinity Stones IMO. I feel that there is something else at work there. Perhaps in some suspended state, alternate reality or realm, dram state, etc.
