The lives of those that suffer from paranoid schizophrenia are well 'documented' in popular culture. One such item you may be interested in is the film 'A Beautiful Mind'. It is based on the life of John Nash, but keep in mind it is a dramatisation rather than a documentary.
There are also a number of 'simulations' on Youtube that may exemplify the horrendous nature of the condition, if you are so inclined to experience them. One such video is this: https://www.youtube.com/watch?v=0vvU-Ajwbok .
I hope I have not taken your portrayed interest too literally!
