Well... since everyone else is sharing...
In childhood I want to say that I had deja vu at least somewhat frequently. I say 'want to say' because I actually have a very difficult time recalling much of any of my personal history including more recent times, and certainly not with much clarity in what I can recall. Anyways, the deja vus from childhood I think were much more the 'dreams happening in real life' version, because I recall other friends saying they sometimes had dreams that basically 'came true' and gave them the deja vu experience when they realized it all during the event or whatever, and I remember thinking or saying to them (not sure which) that I get that rather often also. I do specifically recall moments of deja vu quite similar to what you're all describing also, watching events like a re-run of life somehow, where you know what's going to happen, but usually only as it happens and you can't change anything anyways.
I just so happened to have had deja vu just last night, actually. I was standing cooking at the stove, when I got the deja vu feeling. Phenomena like this are of great interest for me as I can't recall any significant 'out there' experiences or anything happening to me, so when anything remotely 'strange' does happen, I NOTICE. So as soon as I have the feeling, almost instinctively, during or even before I had consciously thought about it, I had that deja vu feeling that someone specific I know was going to walk in the door right next to me. I quickly whipped my head up to look at the door, where I basically was expecting to see this person. It all retained the deja vu feeling right up to the point I consciously realized that no one was there. I kind of did that 'stand ready and wait for it' thing we sometimes do for a minute, and then realized that it was all over and no one was coming. About that same time I thought, 'well, good then! I'm just fine that they didn't come home just now!', and there was an odd negative emotional 'aftertaste' of sorts, but I'm honestly not sure which came first, thought or feeling. The entire thing couldn't have spanned more than about 1-2 seconds, minus my 'waiting ready' bit, yet somehow it was a very...'complete'..feeling deja vu. One of those rather mundane deja vus all in all, but it just kind of struck me. I had an odd feeling between the 'onset' of deja vu and looking up at the door 2 feet away. Almost like the 'a-ha!' or epiphany feeling, actually. I looked up,
knowing I was going to see this person, and had a 'building up' feeling, almost as if you were looking up expecting to see Jesus or something! Then when they weren't there...I think that's what struck me about it. It was almost like a 'Deja Vu, Interrupted'. Weird.
Alright, the deja vu I really posted to bring up to you all is following.
I was at a school blood drive recently for both the small extra credit offered by my anatomy professor and the nice warm thoughts that I'm helping someone who in an emergency will need my blood someday. Note that I am not queesy about needles whatsoever, and have never had anxiety about anything like this at all before. So I'm sitting there, waiting my turn, and actually feeling just a little anxious. Now in my life that could be for any of many reasons, so I never thought twice about it. Now I'm not sure what I was thinking about, possibly something of the Cs/Laura's materials and/or the concepts at least, but I ended up having this thought shortly before I was called for the pre-screening (where they prick your finger to test for iron, etc.), remembering that certain variable-density beings bathe in blood and absorb the required nutrients (someone correct me if I was wrong on that, but I think it's basically correct and it's what my thought was at the time). Could have just been being around blood got me remembering that, whatever. So I shook it off, but the thought not only followed me, but continued on. So then I'm thinking 'Umm..I wonder... no way.. I..I wonder if 'aliens' of any kind take any of the blood from drives, etc. for their own use!?!?'. About this time, the nurse calls me for the pre-screen and I again try just shaking the thoughts off, using the pre-screen and answering her questions to help. After we finish and she gets up to find a spot for me and so forth, I find myself trying still to shake off these thoughts that there might be the possibility of STS beings stealing blood from blood drives and so forth for their own consumption. Might've been a
little bit strange of thoughts for me on a normal day, but I'm weird, so not all that out there, really. I'm not paranoid or anything and normally thoughts like this would've been entertaining for me. However on this day, perhaps just because of the setting, it was upsetting me quite a bit! In fact at this point it was kind of a weird mix between thought/feeling. I was in a good mood, it was to be a good day, etc., this thought/feeling was just annoyingly nagging at me. It's good to note that through the story so far, no deja vu experience, just this strange trip to give blood at my college. So I'm just sittin' in my little blue cloth makeshift booth waiting, and I'm now to the point of 'rationalizing' with myself, telling myself I have no real evidence to base any of this feeling/thought on and that I'm doing good for someone who'll be in need and so on and so forth. Not externally upset, but mentally wondering what's up with me this day. So the nurse finds me a table and leads me over, but nothing is set up, so she says to get comfortable and she'll be right back. So I take off my fleece, hang it and start situating myself on the table and finally-DEJA VU! However, it was actually unlike any other deja vu I've experienced. Literally except for the above-mentioned deja vu, I can't recall any off the top of my head in the last 6-8 months or so. Usually, it's just that weird feeling that 'it's all happened somewhere before', and basically neutral otherwise, for me. I usually don't get emotions good or bad with deja vu. But this time, I actually got a bit unnerved. I sat up on the table and basically in one motion swung one leg up, the other leg over that and reclined to the 'seated lounge' position. As I am very tall and the tables are not, it was a usual, relaxed movement for me.
As soon as my legs had crossed and I began 'lounging' I got the very odd deja vu experience. It actually had nothing to do with anyone around me, which in retrospect was odd since it was definitely the 'deja vu feeling'. Instead of watching things happen and feeling deja vu, even if only about a single event, I just kind of got this split-second flash of a really bad feeling and a semi-mental image of sorts. It's hard to describe, so forgive me if this isn't my wordsmithiest moment. It was sort of a flash like just for a millisecond I vividly recalled (extreme rarity for me) a memory. The 'flash'/deja vu was very dark, much more grey than the room I was in, but just maaybe similar somehow..in structure? Some factor of 'mechanical/ness' was in the deja vu also, but I'm not sure at all how. The table may have been a common factor in some way, but I'm not sure. The feeling that came with was what was unnerving for me. Leaving ego out of it, I'm not scared of much at all. Most of what I get in the way of fear is more that 'heightened awareness cause if something just happens to be in that dark place I'm going to be ready!' feeling than anything. But what I felt during this 'unusual deja vu experience' (ha! there's a 'play on words' word for that, I'm sure) was, if not directly,
much more close to fear.
To the observer, I basically sat down for maybe 2-4 seconds, and then immediately stood back up and started getting my fleece back on. My mind was no longer in any confusion because any thought except 'what the hell??...' was suddenly irrelevant. I didn't know exactly what happened or why, rationally, I might be leaving. All I knew was I had had 'an unpleasant deja vu' experience and that I was very sorry to anyone who might have needed my blood in an emergency one day, but I wasn't staying there any longer.
So yeah! Sorry that got a bit long-winded, but having had a deja vu last night, as well as having a chance to share the unusual one here I just had to join in the fun with ya'll :)
So far, no big thoughts on deja vu so far except thinkin' along the lines of our 'Matrix program change'/'negative feedback mechanism' ideas presented here so far. I'll post back if I come up with anything entertaining!
