Sense occurs in the brain.
For ex. Though it appears that hearing comes from the ear, that is actually the brain translating information from the ear and setting the sound that happens outside the ear to have a certain stimulus and in the ear to be recognizable. Hearing occurs in the top, left, front-back of the brain and can be registered.
There are lots of things you can tap into concerning the brain through the use of 'I am' or 'I are' this.
