my belly moves independently of my body

so my belly moved today completely independent of the rest of me... i guess that happens when you are 5 1/2mo pregnant... it just surprised me i have moments that i think i can't possibly get any bigger and i am ready to get the show on the road and then i think i can't believe i am really pregnant and still expect to wake up any time from the most bizarre dream ever... maybe when i wake up i will have dreamed the cellulite on the back of my thighs too.
