Spouted scripted narratives

1. Does "spouted scripted narratives" mean "read written narratives, that is, read from a written text instead of speaking orally"?

2. Does "which addressed different kinds of haunting" mean "whose contents were about different kinds of media that have surrounded our lives today"?

3. What does "psychic mediums" mean "the people who can contact the spirits"?

Context:

This was one of the many references that inspired Oursler’s Artangel commission The Influence Machine, 2000, an outdoor son-et-lumière spectacle in London’s Soho Square and New York’s Madison Square Park, where he staged projected phantasmagoria consisting of smoke, lights, mirrors and his signature projections of disembodied faces in the park and on the surrounding buildings. These talking heads spouted scripted narratives which addressed different kinds of haunting from the internet to psychic mediums, the work itself combining anxieties about urban space, media technology and disembodiment.
