The best wish ever

Jon came home after that. He still havn't desided what he would do with the rock. So he slept on it, In his dreams he was a Liquid. Capable of bodyhopping people and shapeshifting. His dream was so exotic that when he woke up. Jon had a cum filled bed. He grabbed the rock and said "I wish that my bed was clean and that I suddenly become a slime capable of bodyhopping powers and shapeshifting powers". Now, who to possess?
