Ideas for my film - script and dialogue

The brief for my film states that it should be between 2 and 4 minutes long; although David Lynch has created many shorts before, it was his feature films I was most inspired by, and therefore I had to come up with a way of putting identifiable elements from his feature films into a small short of my own. I decided to combine all my research from a different number of his films to create my script - particularly from Blue Velvet, Lost Highway, Mulholland Drive and Inland Empire as they all seem to follow similar themes and formats.

  One of the main themes involved in all of these themes is death - at least one or more of the characters die. This fits with the film noir style of the narratives, particularly  and therefore I feel it is a good idea to involve a murder perhaps in my script. I think this would be best done with a gun of some kind, considering it has to be a quick, easy death to fit with the short time frame I have to portray the story in.
 I also think due to the time frame that not much action can happen (other than perhaps the death) and so a more conversational piece will be easier to create.

Based on conversation scenes in Lynch films, such as the 'cowboy' scene in Mulholland Drive and the 'gypsy woman' scene in Inland Empire, the conversations work most effective if quite nonsensical, to add to the typical 'Lynchian' dystopian atmosphere. In addition to this, like in Rabbits, if it seems nonsensical at first but there's more meaning to it (all of the lines would actually make sense if they were read in a particular order) then this would be more of an interesting reveal to the audience when they can make at least a bit of sense out of a totally surreal world. I therefore intend to make my script achieve this.
 Another interesting idea which is involved in a lot of his films, is how characters are revealed to be someone not initially assumed. For example, due to dream sequences and actor switches and distorted reality, a character's backstory may be totally different to what the audience is shown at the start (a major part of the plot in Mulholland Drive). This could be a simple concept to create, which I intend to use; this could be done with the characters talking about a person, only for it to be revealed that one of them is in fact that person. 

 The whole of the dialogue should be slow and exaggerated, as this is what typical Lynch films are widely known for. Again, this adds to the dreamlike world in which the narratives are set.
