Someone I know says their hands shine in lucid dreams, however it is not limited to hands, it’s just that the glow is brighest around the hands. The glow itself is like a thick layer of, ermm… glow. (yellow-ish by the way)
However other people do not have this sort of shining around their hands or dream bodies.
Any ideas why or in what way people are different to have this distinction?
I dont think that person is different in any way, the glow must just be a dream sign of theirs. I mean, I’m sure anyone could create this glow around their dream bodies if they wanted to.
I’ve heard of this sorta thing before… and I believe it has to do with the numbing that occurs in the body, mainly the fingers, during hypnosis. 
I’ personally dream stuff that’s directly influenced by my real senses often.
The mind is a wonderful tool and if this person is to see glows around them selves it could respresent power.
Other may tell you it is an aura, energy, a trick of vision, lack of clairity of the mind, etc etc.
In many of my lucid dreams, when i am over come with emotion of some sort, a glow overcomes my body, focusing on my hands if I am going to use them for something, stoping time, light beams, moving anything or some more advanced lucid dream experiences, some of my most powerful lucid dreams have had a glow around my self, its also a good way for me to identify dream characters from other possible dreamers or more powerful internal thoughts.
Everybody is different but i suggest you ask your friend what they feel about this glow and what they think it means and to wait and let the answer come to them, when it comes to dreams, more often then not the answers will always come
yea, sometimes i need to use flame punch when i fight in lucid dream 
i would say it has to do with a person’s aura. Or like mentioned above, it might be a dream sign.
