Is it normal to have deja-vu paradoxes?

I've noted how often users have posted about having ample deja-vu. While this deja-vu has calmed for the moment, I would like to explain these seemingly infinite deja-vu paradoxes I've had. For many years, this feeling has come not only as a suspicion of a previous situation, but a knowledge of everything that happened in each repetition.

For example, perhaps I'm typing a document when I suddenly receive the impact - "Here it is again; I've typed this document before, although I know it's about a new subject entirely."

I would then realize how I had handled this situation before: "The first time I felt deja-vu on this document, I tried to figure out why. The second time, I tried to shake the feeling by ignoring it. The third, I wanted to break the chain in time by changing the wording in the essay... I think. Was it third or fourth? On one of them, I'd almost stopped the feeling when I raised my left arm to ensure any future deja-vu that this has happened. Last time I was in this situation, I really dove into thought about the time before, wondering how that last method would ever work logically."

At this point it's stressing me to try and comprehend this string of deja-vu. After about three occurrences, I start to lose count of the number of times this particular situation has happened. I have nothing left to do but find some way to make the feeling stop; if all of those methods have failed before, then I need to try something else. I stop trying to figure out whether I've really done this that many times, or how any of it is possible. I stop trying to put logic into it. The tangled web of time in my mind has become too chaotic for that moment - there's got to be some form of relief. I start looking around for something the past didn't have... Aha! I have successfully found it, and thus rid myself of the madness. It's a shame that by doing so, I'd also created a new method for the future to chew on - the endless deja-vu paradox continues.

I apologize for the length. While I've felt several of these deja-vu strings, they have various lengths, and each occurs for one specific situation. That being said, Is it Normal to feel such a complex type of deja-vu?
