What is the relationship between lucid dreaming and IQ? Or indeed is there one?

Are you more likely to lucid dream if you have a higher IQ, or the other way around? Or is it to do with the brain hemispheres and if you are a creative person or a logical person?

It seems to me that lucid dreaming is a creative art, so I would think that if you are more creative (as opposed to logical) then it would make you more likely to lucid dream. Saying that though, you need some sort of logic in your dreams to realise you are dreaming right? So do you have to be logical as opposed to creative? Or maybe you have to be both?

My brother lucid dreams without trying, he is of average (or slightly below) intellect, but the reason he lucid dreams could be to do with the substances he takes-lots of alcohol. I know he doesn't sleep well and when he finally does, he has strange dreams that are often lucid.

One of my friends can lucid dream naturally and she is pretty clever.

I tried to lucid dream for ages and have finally been able to do it this year, but I am definitely not a natural LDer . I consider myself to be of a slightly higher than average intellect. I am quite a creative person, I play music and draw, but I am not outstanding at it. I think I'm pretty balanced creatively and logically, a bit higher than average for both.

So what do ya'll think, does IQ have anything to do with how easy you find it to lucid dream, or does it not matter at all?
