Wow, this is hilarious and at the same time disturbing. Not only is this one of the most perfect ways for such a entity to merge with someone, something horrifically merging with someone is one of the best ways to freak me out.

Ever seen that one Hellraiser movie with the two twins getting laughy-taffied together? Yeah, I can handle most anything else in horror genres, but that always sends shivers down my spine like someone being a huge dick with an ice cube.
