Personally, I don't really think count Dracula is hiding in your rosebushes, but you could be attracting negative energy and energy can be interpreted in many ways. You give it a shape because you're uncapable of seeing it's real form, and that shape depends on your believes. That's why you would probably see negative energy as a vampire, while I might see that same energy as a giant wasp. Negative energy attracts negative energy, so try to become more balanced in your life. That will make 'them' lose their grip.
