Swallowing Hair

woke up making a choking sound because of a dream where I had swallowed all this hair and gunk strung together like the gunk down a plughole, and I was pulling it out strand by strand from my throat

dreamed I was in a huge, enclosed city with a glass ceiling, on the run to or from something, and saw a huge amount of ice from the ceiling detach itself and tumble on to a crowded part of the main street, squashing and killing dozens of people and flattening them into a red mush - I was horrified and kept walking with my hands over my face, eyes wide.

I was on the phone to a client from a job a long time ago and he wanted to talk to David, but David was out of the office and wouldn't be back till Monday. Martin didn't want to talk to him and made me fob him off. This made the client angry and he accused us of not knowing what we were doing. I got annoyed about this and asked him if he had a problem that needed solving and he said not right now, so I asked him what was the matter then. He said that to explain he would need to show me a demo movie from his company. My computer was in pieces on the floor and by the time I had it almost put together again the movie was over and it was time for the client's lunch. He was angry that I hadn't managed to watch it. He was just angry. Is this a metaphor?
