The last works well with studying! I always studied right before sleep and would even put my book under my pillow so my subconscious self would be 'reminded' of my studying. I regularly would wake up going over the details of the information.
This is hilarious! I just may try it. So few people have my name so either they are calling my name or I can add one more person to my still short list of other people named Glenna or my even shorter list (still on one hand) of people named Glenna Jo. :-)
