Lucidity in naps?

Hiya! Well I was wondering, what's the best way to acheive lucidity in naps? I am usually napping (school and swimming take the energy out of me bad...) and I would like to know what would be the best way to lucid dream during a nap. I've seen that you can WILD a nap... But how? Or is there a better way to do it?

Thanks. =)

There are WILD tutorials in the tutorial section of the forums. A good one for napping would be MILDs I think.
