Loved the concept of anxiety... the bed scene kept me in stress if he suddenly came on the bed at the end... I even tried looking off the bus and got scared... not expected that. I loved the tension.
if you ever try remaking it, the shop could be even bigger, like rearranging things on shelf and him coming from any corner to scare, on the bus, like changing seats; and in-house, like running to close the windows and doors ...but for the jam, this is pretty well executed
