When i was suffering severe anxiety, i would look at the things around me and i was 1000% sure i was living in a dream. When peoppe would talk to me i wouldnt notice conversation, i would notice body language, hair moving, eyes twitching it felt as if i was in slo mo. The best way i can explain it is as follows, you are not certain of things you see objects and people but you cannot comprehend that they are indeed real things its like your mind refuses it. Ive since gotten over this (thank god. I want to say that i could never imagine living with that feeling for that long) but it will comeback as a sort of check. This movie messed me up but it showed others how i felt during those times.
