The spins happen because of an odd effect alcohol has on your ears -- specifically, on three tiny, fluid-filled structures called the semicircular canals.
Inside each of these canals is a fluid called endolymph and a gelationous structure called the cupula , which is filled with cells covered in fine, hair-like stereocilia. When alcohol gets into the blood stream, it slowly diffuses into the endolymph, and makes it more dense. So the little blobs of jelly begins to float, and this stimulates the VIIIth Cranial Nerve, giving you the impression that your bed is spinning. As the night wears on, the alcohol gradually diffuses into the blob of jelly as well, making it as dense as the liquid it floats in - so the spinning sensation lessens.
After a few more hours, the alcohol begins to leave the endolymph, so now the blob of jelly is slightly denser, and you get the impression of spinning in the opposite direction.
