I've played/read/watched a lot of things that attempt to capture the feeling of being in a dream, but this takes the cake.
Like trying to run from a threat, but the harder you pump your legs the slower you move. Like pouring your heart out to a loved one but when you look up at them they've morphed into someone completely different. Just, beautiful writing and visuals paired with a soothing classical soundtrack that helps lull you into the dream scenario even further. Amazing work.
