My thoughts 

Although interesting, this film poses two challenges 

(i) Without prior knowledge, audience might be caught by surprise. Without a main plot, one has to try gather what the entire film seeks to convey. 

(ii) The humor/black comedy/satire/etc is only powerful and punching probably to the Swedish (how about Europeans in general?! I am not sure) because they have the correct context, culture and capacity linguistically to appreciate it. From the response (e.g., laughter) during the film (NO Q&A), I presume few locals can truly get every single joke. 

Like the beginning two vignettes, one woke up suffering from a nightmare, whereas the other complained about unfulfilled dreams ... I wonder, whether the film turns out to be a dream or a nightmare, you shall have to go watch for yourself!
