I dreamed I was visiting my mother (who was living in what looked like a four star hotel complete with shops in the lobby) and I discovered that she had taken some friends across the street to the local Scoopies* and treated them all to ice cream. Except all she had in her purse was a Provident Bank CD (certificate of deposit) for $10,000 and the ice cream place had not only accepted it but had given her a couple of hundred dollars in change and given her the rest in Scoopies' Gift Certificates. I was on my way across the street to try to straighten things out when I woke up.
*Scoopies is actually an ice cream place in New Mexico. And of course the dream was way more fluid than I have described. She didn't have a purse at first and she had dropped a large roll of money into a glass of water. I tend to have dreams that resemble the way I think when I write. Large roiling masses of stuff which sort of refines itself towards coherence. It's one of the reasons I am suspicious of dreams in stories.
