When I look down at my hands to stabilise, they are most certainly not the the same as my waking hands. The patterns and creases I would see in my normal hands are distorted to the point where instead of being made up of lots of little lines, they are composed of many circles of all different sizes. Occasionally I have a couple more or less fingers than normal, but the patterns are always different. Interestingly though, they are only unusual when I am lucid, but that's probably because I am more observant when Lucid. What do your dream hands look like?
