I have a superior suggestion for you Chaotee.
Make or acquire an object in which to create a thoughtform to inhabit it.
Place it somewhere in your town someone is bound to come across it and create a mental link to it and a warning system and everything so you can track its progress and interaction with others.
Have it programmed to latch onto and influence someone who will take the object home.
Begin chaotically influencing them, poltergeist style, with the object (perhaps a doll) being the transmission point.
Real magick nigga, not just silly posters.
