I just created a spread sheet showing dream imagery sorted by the night of the week. There are already four items that match different dreams that would not be likely to appear in waking life. Being aware of these dream signs may help to wake me within a dream.
I am a bit shocked to find multiple instances of multiple selves. I thought the second time I mentioned them here was the first time I experienced that but my first recorded dream has a record me playing basketball as I watched myself.
