Either that, vitamins or practice.
Yes, rubbing your hands together while dreaming is used to increase vividness in your dream.

But this would be easier to achieve while Lucid, so if you just want a vivid dream, then you could try that apple juice thing. Although, I've never read that apple juice has done anything to help with vividness in a dream.
