Does anybody else have dreams that relate to each other and/or deja vu in dreams? Like having dreams continue from where you left off, or at least think that you have had a dream continue from when you left off?

To be clearer, I have had a dream once where I cleaned an attic. I took all sorts of old stuff and packed in in giant garbage bags. Several months later, I had another dream where I stumbled upon this attic. It was perfectly clean, and there were giant garbage bags piled all over the place. It was exactly the same as my last dream.

And my friend, apparently, has continuing dreams about a box that I drive. Almost any time she has a dream, The Box is featured in it. They're not all the same, though - in fact, from what she tells me, it's like an ongoing story.

On a different note, in most of my dreams, I feel like I have experienced the same thing before (only I haven't actually). Like one time, I was in the middle of this church basement with some young girls. In my dream, I distinctly remembered being there with those girls before, and promising to come back to visit them soon. However, when I woke up, I realized that I had never had a dream about anything like that before. Anybody else?

Sorry for a long and confusing post, but I'm interested if anyone else has experienced either of these things.
