Apologies for the bad acting at the beginning haha.
The main Philip K. Dick books I recommended were:
-Do Androids Dream of Electric Sheep?
-Ubik
-The Man in the High Castle
-A Scanner Darkly
If you want to read more about Ubik, check out Time Magazine's blurb on it when they named it one of the top 100 novels of the 20th century: http://entertainment.time.com/2005/10/16/all-time-100-novels/slide/ubik-1969-by-philip-k-dick/
