Before viewing, here's some gloss.
Look for how he says right off "lost my mind" like "connection dissolves." There is no "lost" and there is no "mind" shown.
I wouldn't even think of that.
"There was something so pleasant about that place. Even your emotions had an echo" seems to be shown as "satisfied, feeling, my feeling, your feeling."
The therapist says, "Think twice, warn warn warn warn warn."
My favorite part, "who do you, who do you, who do you, who do you think you are, you there," really is shown that way. It's perfect.
And my second favorite parts are "just like you" and "I want to be like them" he uses the same technique of "same-o, same-o" first between himself and the doctor and then between himself and "those out there." It's very effective both directions.
Lastly, his playing the part of himself and the therapist and the guy in the cell writing on the walls is just splendid.
It's all very creative and very well done. Please enjoy this wonderful expression as much as I do.
