Visions in the Dark

I can only remember a fragment of the dream I had last night, but it is the first dream I have remembered for a very long time.

I was either in school or in a store of some kind and I went up to a man who was sitting behind a table selling things, but he only spoke French and we could not understand each other. I can barely read French and I certainly can not speak it in waking life, but for some reason in the dream I started "faking" what I thought was good French and apparently it was because the man behind the table and I had a long and cheerful conversation with me. I knew by the sound of it that we were speaking French, but I had no idea what either he or myself was actually saying.
