Complicated answer considering sometimes I convince myself that what I'm thinking is untrue, and will forget all about it when I "find evidence" that makes me feel whatever I'm thinking can be true. For example, I'm currently convinced that (though I've made many realizations to the contrary) I am somehow connected with multiple realities and can see and hear things from those multiple planes. Sometimes the info is from a reality so similar to my own that I'm cabable of "predicting" what happens in this "main" reality. My therapist and I agree that this is an illusion. I am currently inclined to disagree with both of us.
