Hi, all. A weird question popped into my head this morning, after I swatted W across the snout because I dreamed that a wasp was bothering me. I know that it wasn't really a wasp because it was brilliant crimson. That reminded me of the olden days question of whether or not people dream in colour. I know that I certainly do, but it raised another question. Can someone who has been colour-blind (grey-scale vision only) his entire life dream in colour, or does it have to be something that has been experienced in waking life? I'm pretty sure, for instance, that I've never dreamed in UV or IR, which I figure is because I can't see them normally. Any colour-blind PFers care to enlighten me?
