Illusive itch

I get all snuggled in bed. Find the right spot after much tossing and turning. Fix the blankets and sheets just right and the pillow fluffed perfectly. Just on the verge of my sleepily land dreams it happens. I get an itch. On my foot. It had to pick the farthest part of me. I have to disturb everything that is making me comfortable. Which I do. Take care of the itch and try to get comfortable again. But nooooo. Now the itch begins to travel. It goes to the back of my leg, to my back,to my left arm then my right. It drives me to a wide awake state then stops. That is until I get comfortable again. Do you sometimes get an evil itch during the night?
