RW, if you ask at the bank they can give you empty rolls for your change mountain, so you can sort it, roll it, and exchange it for more manageable paper bills.
Tybalt, first you must eliminate other possibilities. Did you go to bed hungry? If not, did you have indigestion? Did you try some Tums? Have you recently undertaken the study of a foreign language? You weren't experimenting with naughty substances, were you? We don't judge here, it's just that if you were, and you had odd dreams... well what would one expect?
