Its on your mind because they put it there. They do this to to keep you ocuppied with its foolishness so you'll waste time worring about it instead of fullfilling your real God given purposes in life. It also wants to frighten you to the point you'll become afraid to pray and try to confuse you to the point where you don't know if God is with or them. You need to get rid of them for good by pleading the blood Jesus otherwise they're think you like entertaining with them and they'll become more of a nuisance. I'm not trying to scare you but you need to firmly send them away. They realize that we become amazed by their existence and they play on it if for no other reason but to waste your time. Think about it, how much time have you spent already trying to figure out whats going on and is it really happening. This happened to a friend of mine and it nearly drove her nuts and me too. Finally after telling her minister she was able to send them away. Plead the blood of Jesus. Tell it next time " I rebuke you with the precious shed blood of Jesus Christ." Demons are working overtime tryin to get peoples attention. Some people think they're aliens and other cosmic being. They're just plain old demons. Good luck and God bless U.
