I never have before, but I had one last night for some reason. I dreamed that I was on a road trip and my brush literally fell apart, and I was in a panic because I had only shaved about half my face. It had a very similar feel to those "naked in school" dreams in terms of the anxiety. I mean, in real life there are ways to improvise in such a situation. I'd go buy a can of Barbasol or whatever if I had to, but you know how dreams are.
Don't ask me what it means, I'm no scientist. Maybe a bad shave is my new greatest fear?
Ever have a shaving dream?
