Skarsgård said that he returned home only to start experiencing "very strange and vivid Pennywise dreams." He explained to EW that Pennywise was visiting him in his sleep: "Every night, he came and visited. It was in the shape of either me dealing with him, sort of Pennywise as a separate entity of me, and then also me as Pennywise in circumstances that I didn't appreciate. Like, I'm Pennywise and I'm really upset that I'm out in public and people are looking at me."
Regardless of this creepy phenomenon, Skarsgård reprised the role in It: Chapter Two.
