Since I have been keeping a dream journal (11 days now) I have noticed something interesting. Occasionally I will be unsure of the continuity of things. I.E. "Is this a new dream or a part of that one?" Then last night, the real world gets involved and I get even more unsure. Last night I recalled 1 dream and 2 fragments. The dream was lucid, my third and most realistic yet. Rather than type it all out I'll just tell you what you need to know.

Dream 1:
I had been watching a tornado form and it suddenly became wireframe. This struck me as odd so I did the pinch your nose and try to breathe RC. I could indeed breathe. I was kinda like "whoa" so I did the RC again, and I could breathe through a pinched nose. At this point I became lucid, after a bit of fuzziness it became the most realistic lucid dream I've had yet.

Fragment 1:
I was in a city somewhere and I remember doing the nose-breathe RC, trying to do it covertly because I was with someone.

Fragment 2: At some point during the night, I attempted the nose-breathe reality check. Evidently I tried too hard as I remember waking up very briefly (like 1 second)(Actually it was more like becoming aware of my physical body whilst in a dream.) Either this goes in Dream 1 and I recovered from it, or it goes with fragment 1.

Dream 1 and Fragment 1 are unrelated, but Fragment 2 goes with one of them, or something completely different. I have no idea but I definitely remember it. My question is: Is being unsure of continuity like this common? Is it something you have experienced? It's not a big deal to me or anything but it is an interesting
curiosity. I just wondered if anyone else had "misplaced" fragments like this.
