(This isn't my dream; it's one of Seven Answers).
arrived at a house unexpectedly, I think, and there was going to be a party that required smart dress. The clothes I was wearing were not suitable but I didn't have anything else with me. I went to a bathroom and washed my hair in the sink. People kept coming in and looking disapproving. Afterwards I went into another room and there were lots of people modelling clothes to wear. Most of them were too casual and ethnic but I managed to choose something I thought was suitable.
Then I was dancing at the party with a friend. She told me that a man dancing towards us had been eyeing her boobs earlier and calling them doggies. As she told me he came closer and I looked down and saw that one of her boobs had slipped out of her dress and her nipple was showing. The man danced around us saying nice doggy! Nice doggy!
Eventually we managed to get rid of him and then abruptly we were given some frozen lamb to prepare for cooking. We were discussing how to cut it up and then we were being offered a whole cooked sheep carcass to eat. I must have looked a bit confused because someone reached inside the carcass through one side and slid out a baking tray full of cooked offal. That was when I woke up.
