I had a few last night but the one I remember most clearly is this:
I was travelling somewhere and found a huge thrift store. It was packed from floor to ceiling with incredible stuff - I kept finding things I liked but every time I asked the owner how much they cost, she told me they weren't for sale. I was starting to get really frustrated and then I realized that she meant I could just take whatever I wanted. Upon realizing that, I felt guilty for wanting so much. I finally found a small blue vase, thanked her for it, and went on my way.
