I had a dream about this guy and he was called a Dimensional demon. He looks friendly at first but thats what he wants you to think. What he does is that he lures strangers to come along with him to explore the dimension hes in and once they are happy, he would ask "Are you satisfied? " and if you answered with "Yes I am satisfied " or something similar, then he replies with "Very good..." before he devours you! Basically giving you your last happiness before you become his meal. Oh and he is capable of opening portals to other dimensions just by tearing a hole open with his claws.
