Freud Get Out of My Head

Freaky dream of the week: It's a sci fi. In space - very large spherical battleships. I've thankfully forgotten most of it, but here's the weird part I can't forget. For some reason testicles provide some substance that powers weapons. Grandma L. shows up with my dead Grandpa's huevos, which have been preserved by the miracle of modern science and recommends they use the smoother (i.e. hairless) one of the two, 'cuz when she and Grandpa used to have sex, she'd have an orgasm every time he "used that one ". WTF????? Am I channeling Freud or something?
