Right now in Dracula, Lucy is getting up in the middle of the night and is acting strangely. Her peculiar behavior can relate to horror movies like Paranormal Activity. In those movies a character usually gets up involuntarily in the night and walks around the house, similar to Lucy.
Right now, Jonathan is still trapped in the Count Mansion. This situation reminds me of the book Mockingjay when Peeta was trapped in the Capitol. Peeta was captured and tortured by the people in power and felt like he was in a nightmare. Jonathan feels the same way because he’s been locked up in this room and has no freedom.
