My Nan uses the word Dizzy a lot. If someone, such as the doctor or a friend asks her a question that she is unsure of the answer to she'll tell them she feels dizzy, they are dizzy, I am dizzy, her pet bird is dizzy. I haven't quite got to the bottom of the word that she is replacing with dizzy but she 100% isn't saying that is how she feels as she never uses it in the correct context, it is as though, like some of the others, she means a word but cant remember it so replaces it with dizzy.
