This quote from the telepathic cat is *wonderful*.

I've had the experience in dreams of having a waking-world mentality, that is, of being unsettled and confused by the fluid shift in situation, and yet not (as more usually happens) realizing that this means I'm dreaming. I recall in one dream thinking that maybe it did mean I was going crazy. As when I've worried about that in real life, my primary reaction was to try to act as inconspicuous as possible so as not to call my (possible) condition to anyone's attention. Meanwhile, I expended energy trying to make sense of the situation. Eventually my mental state became more dream-friendly, and then the shifts and fluidity no longer bothered me.
