I had a Dream ... Again

Had a dream where I was trying to get change from a change machine. I put in a bill and various coins appeared, but it was never the right amount. People around me were taking and adding coins, and the total was never right. I kept trying to grab the coins, checking the total, trying to tell everyone to stop so I could get the right amount.

As I awoke, the clear single thought occurred to me - "I need change!"
