No pun intended - sleep is a precious thing ... and something we know little about ... or remember nothing about! Mostly and most of us that is - but if you wake up and realize that something is off ... well you might wonder what went on in the night ... and that is where and what this is aiming for.
The main actor is well known in the British Film industry - at least most will be aware of him or have seen him in something. His job is not really thankful, there is not much dialog (and the work zoom call thing seems more of a distraction, but symbolizes "normal" life I reckon) ... and that is I guess something some people may have issues with ... the pacing or rather the length of the short movie.
It still works - you just have to have some patience ... I don't think this will surprise to many people ... but it is well done and told nonetheless.
