The woman in my dream was very, very tall in her magic shoes. Why?

I was in the cafeteria of a ski resort. Lots of people were walking around in ski jackets and munching on hot dogs and nachos. Somebody informed me that I was needed to star in an adult movie. That wasn't my normal job, but I said OK, I could use the money. The woman who was going to co-star with me came waddling down from upstairs in her clonky ski boots. She was normal height for a woman, about 5'8". She looked just like Jennifer Connelly, except that in the dream she seemed to be someone I knew from my everyday life, and with whom I seemed to be friends. In her hands she carried a pair of high heels. They just looked like normal shoes, but when she put them on, they made her about 8 feet tall. The top of my head came to the bottom of her breasts. The guy who was supposed to direct our movie was sitting at a nearby table, staring vacantly into space. It seemed like we shouldn't bother him, so the woman and I decided to wait. We could pass the time by making out. She took off all her clothes, except for the high heels. I could only kiss her belly, because that's as high as my mouth could reach. When she wanted to kiss me, I had to look up and open my mouth like a baby bird so she could spit in it. Most of the time, she missed. Soon, I was dripping with her saliva. But I didn't mind, because that was just how she kissed. I started rubbing between her b�tt�cks. She seemed to enjoy that a lot, and said that we should do an�l s�x for our scene. I said OK, but then suddenly her b�tt was covered with sand, which disturbed me. It started crumbling off her and making a sandpile on the floor, like in the bottom of an hourglass. Then the director came over and said it was time to film our scene. He wanted us to shoot it outside in the snow. I panicked and woke up.
