At the end of his life my husband was on morphine
. He was irrational, seeing and
hearing things, talking nonsense..as in telling me not to ride my bike to town..#1 I don't have a bike, #2 we lived 18 miles from town. He also got very agitated, and paranoid. Morphine can also make a person violent. Your relative should go back to normal once she is off of the morphine and it clears her system. Good luck, and just agree with her, whatever nonsense she is spouting.
