I vote "A" ... or a modification of it, at any rate. Recall simply is another way of saying a dream is remembered, thus indicating that you have created a memory of it (I know this is kind of an obvious statement, but the rewording of it brings attention to everyone - myself included - to why we use these names on DV.)

I actually get this phenomenon all the time. The more I get used to recalling, the more I find myself confused! (haha)

Another thing I get, is I'll have a dream, and in it, I'll have a dream memory. I'll "remember" something that has happened with a person before (not actually happened, and not even a dream I've had before.)
