Another HVN Film Night - Friday 22 May 8pm BST (UK time)
Thank you for your response and brilliant question, I think the example you have does an excellent job of ticking a few boxes, one it's a personnel testimony based upon someone's experiences of psychosis, two it's in the style of a indie short as there are lots of good examples upon YouTube or Vimeo, which to draw influence from, though in an ideal world members or willing participants would with the help of known NGO participation make and produce small vignette film's that go where ever the participants want to go, some could be just an interview some could use more imagery, it would be an open event like that, ( I hope you can get what I mean).
Also, you could include the current social distancing measures within the event by going online, there could be a Skype discussion after to accompany the showing of short films and what they mean.
In regards to your questions, I think the tricky parts for me would be several, one the actual daily experiences of being a voice hearer, as most people don't have this normality and view it as evil, scary or drug-induced. Next would be the environmental aspects of being subject to mind games, and dodgy surveillance measures whether by the service provider or by malicious rumor-mongering (Snapchat)
I suppose it would be the gaslighting or the actual voices themselves, though you would have a field day using creative methods to explain it to people and other like-minded sufferers.
One idea could be to use a radio host to be the part of someone's voice and have a person receiving the messages, you could move from one scene to the next not realizing that they are the same person until the ending.
Something like this..
