shadowofwind is completely correct - passwords do not work unless what you feel about the password being said is the same as what the person who is receiving the password. I theorize that dreams are pretty much made up of pure energy, so everything that we think we perceive is just symbolically filtered down in order for us to visually make sense of it. I tried a password system once with my daughter in the early days - a random word: I said to her 'giraffe' she received 'unicorn' - make of that what you will!!
