Did not know about the second definition of reality at all. :| Certainly gives it all a whole new perspective...and after that oh man do the goosebumps start getting induced too...
I'm not sure the final scenes' really necessary, when you open the door and see the robot. Without it you wouldn't be sure if the experience was real or not at all. If they were human or not. If the definition of reality applied in just one or both ways, not being real at all or just being a very unfavorable 'reality' as such...
Loved this though. The emotions spike after the definition, and the animation/fluidity/atmosphere is just amazing. Great work. Really lets you immerse yourself in this alternative... reality.
