"Interrogator": "What was the reason behind hallucinating?", 
"Interrogee": "So Robert was hallucinating because his sister died on her wedding day. She tripped over her dress, fell off the stairs, and hit her head on some wooden stool and died. After that, Robert took her body and buried her in her backyard. But Robert had cut off multiple limbs of his sister and he was continuously spending time with her limbs like her legs and foots, and he was starting to have hallucinations now."
