Your question is interesting, but not quite clear. Do you mean that you feel you don't have a human soul and want to have one? Or that you feel you would like, in some way, to 'own' the souls of others? In either case it sound as if there is something you feel is lacking.
What is a soul? To most religions, it is the essential part of a person, an essence that survives death. But even if you don't believe in a 'soul' in that sense, most people have a sense that each one of us has something unique, something that is 'really' us; which is another name for our real selves.
Do you feel 'unreal' in that sense? As if you lacked something that others have? If so, you are not alone - it's quite normal to feel different or as if something was missing. Perhaps it's because most of us can easily imagine an ideal, but know that we are very flawed. So from your question, I'm not sure if you need help; but if you still feel that you do, please ask another question with a bit more detail and I'm sure someone will be glad to help you.
