I once spoke to someone in a recurring lucid dream, and asked them if they realized they were a part of my subconscious. I was consciously trying to see if I could predict their replies, as I knew I was just talking to myself, but I couldn't. Amazing...I have heard many times that you cannot read in dreams. That's not true... I read in mine all the time. I pay VERY close attention- They are real words, made of real letters. So much for that.
