Everytime I try to go to sleep black spot appears in my room

The black spot is about the size of a basketball it pulsate with dark light and emits strange noise, the first time it appeared I decided to ignore it but after it kept appearing every night I approached it out of curiosity and touched it, after that I felt sick so I went to the hospital, the doctors ran some tests and told me that I was possessed by a demon, they told me that there is no cure but I could learn how to control it and live a normal life, I went to a priest and he taught me how to control it, after a week of training I can control it but it can only do stuff that I can do myself so I really didn't think it would be of much use until I went to a fraternity and possessed the brother that was guarding the keg and made him fill it in my car, later that night we were surprised to see that the keg was still full, we kept drinking until I heard a car crash I went outside to see a car flipped upside down on the floor and two people lying next to it, I possessed the police officer that showed up to the scene and made him write them a ticket and let them go with a warning, I possessed a professor and made him give me a 100% on an exam I didn't study for, I possessed a hot girl and made her sleep with me, I possessed my boss and gave my self a raise, everything was going great until that day I needed to report for jury duty, I couldn't avoid it so I decided to possess the judge and dismiss the case, when I possessed the judge I suddenly felt a sharp pain in my head and passed out, when I woke up I was in a cell and there were 2 men in suits next to me, they told me that possessing the judge was a mistake because the judge was already possessed and when two demons possessing two humans fight the weaker one loses possession and is sent away forever and since I lost the fight I will be sent away forever at the end of the week, I asked them what should I do to prevent that and they said that if I possessed a being stronger than the judge then I could get the judge to reverse the decision and set me free, they told me that they couldn't help me anymore and left me alone in my cell, what should I do?<br><br>Edit: just woke up and wow this blew up, I'll update you guys tomorrow afternoon, thank you all so far your comments have beenchalk full of awesome ideas I really appreciate them
