Speak to them and "Shake the Fungus". He will respond in one of three ways: He will either ignore you as just another hallucination (try again), wake up and head off to his work place (giving you his Psychedelic Fungus Spore) or he will decide you are an invader, become aggressive, and attack you. Kill him to get his Psychedelic Fungus Spore.
