> It seems there is either some process in the brain that actively erases dream memories, or that dream memories are somehow stored differently in the brain than regular memories and only appear as the same thing to the consciousness. There's a fairly simple model that is consistent with this: Nothing is committed to long-term memory while you are dreaming, so when you wake up from a dream, everything is in short-term memory only. Unless you make an active effort to commit it (which you're used to happening automatically), like writing it down or otherwise thinking hard about it, it will simply vanish once you use your short-term memory for something else, like moving around.
