Sure, but ONLY actual nighttime dreams, and only the wildest ones, like when your head becomes detached and floats away like a balloon and you have to chase after it, or when you're under threat by an army of vicious tax exemption forms that have been origami-folded into scary shapes, or when you're trying to give a speech at your local soup kitchen but you open your mouth and your voice comes out like a frog croaking and then you notice your pants are missing, or that one where you dream you're eating a really nasty marshmallow and you wake up and your pillow is gone.
Any mundane dreams like winning the lottery or marrying a supermodel never come true.
I wish... er... I wish to marry a supermodel. Why not.
