Deja Vu vs. Precognitive Dreaming.
I completely reject the theory that it's your mind reading/writing at the same time. I have very clear memories of conversations talking ABOUT the dream, and THEN experiencing the "Deja Vu" from it.
I "recognize" people I've never interacted with pretty often. I don't mean that they have a familiar face, but that I remember seeing them, sometimes even conversations with them that have never happened. This might just be that I live in a small town, except that conversations bit.
I could swear that I've seen things before they happen, but I usually forget about it, and when it happens, I get this really f-cking infuriating feeling of deja-vu. Also, when I'm gaming, especially FPSes, I usually have a good sense of what's going on, and I have a higher reaction speed than normal, but that might be years of skills accumulated.
Also, I can usually tell when a TV or something is on, even when I can't see or hear that it's on.
Deja Vu- I was annoyed by it a few times, especially when it's a looping DV (when you have it repeat, and repeat the experience, and realize it happened before, and you predicted it and experienced it multiple times before; and even lampshade on it's happening (which also is predicted by the DV). Had it happen a few times; and even screwed around with it temporally (Not temporarily. Screwing around
with time, not for a short amount of it.) by allowing my future self to make note of it all, and even announce the details. Upon the DV happening, I did the exact same thing down to the letter). One interesting thing I noticed with my DVs was somewhat inspired by reading some Dominic Deegan. I get DVs that are monochrome, then at that point, there will be a choice that will divide my path of experience (and essentially split into a personal alternate reality); I get DVs that are intensely colored (or high-contrast, but full color), then I assume that realities are merging, and no matter what choices I have been presented with in the past, this is a guaranteed result of any of the choices in alternate realities, or regardless of past decisions. I dunno, it's bizarre. I guess my best explanation/summary of it could be, B&W = Destiny, Color = Fate; in the case of Deja Vu.
As for TV awareness and such, it could be that you're electro-magnetically sensitive. Kinda like a hammerhead shark. You can sense electricity, and know something is on or alive. I mean, I can use that sense, along with seismic sensory to tell if someone is pulling into the driveway, while I'm in the opposite side of the house where you normally can't notice anything going on in the frontside. Heck, it even helps in recognizing whose in the house just by the footsteps.
Now for what I can't explain; why do I do, or come up with, this crap always when I'm bored, and not when I'm supposed to be creative?
