Did you read something about him as a person? He was a profoundly weird person (one example from wiki: "Dick alleged that Stanisław Lem was probably a false name used by a composite committee operating on orders of the Communist party to gain control over public opinion, and wrote a letter to the FBI to that effect"), and that weirdness seeped into his novels. I think you could try one of his semi-autobiographical novels (https://en.wikipedia.org/wiki/A_Scanner_Darkly https://en.wikipedia.org/wiki/A_Scanner_Darkly or https://en.wikipedia.org/wiki/Radio_Free_Albemuth https://en.wikipedia.org/wiki/Radio_Free_Albemuth) to see where this weirdness in the more known novels comes from.
