If you delude yourself, you let yourself believe that something is true, even though it is not true. The President was deluding himself if he thought he was safe from such action We delude ourselves that we are in control I had deluded myself into believing that it would all come right in the end
To delude someone into thinking something means to make them believe what is not true. Television deludes you into thinking you have experienced reality, when you haven't He had been unwittingly deluded by their mystical nonsense. = deceive. to make someone believe something that is not true = deceive (deludere, from ludere )
