Once, in a dream, while talking to a friend on my portable phone, I told her that I was gonna call her back cuz I wanted to switch phones.

I woke up (not realizing it was a dream) with the intention of making the call-back to her, and to continue our conversation. But she'd have no clue about it, I finally realized, because our initial conversation didn't really happen. I got a little aggravating thinking that I have to address all the topics all over again to get that conversation stimulated...
