Why & How do you explain that we humans experience what's called 'Deja Vu'?

I am not sure if deja vu can be explained well enough. It is more of an experience that we have to... experience. Sometimes it is just the feeling of how the day is going. Maybe you look out of your window and see a truck go past, and you saw it before. It is when events seem to be aligning in a familiar way. It also can be when feelings seem to be aligning in a familiar way. It can be the feeling of, "I've been here before," or "I've seen this before," or "I've done this before," and it feels somewhat out of place, but you cannot recall the event where you were physically 'being there' or 'doing that.' As I said, it is difficult to explain.

good day... I haven't experienced it yet but I do hope one day just for the experience of it.

I had a few deja-vu, the latest one was a couple of years back, I remembered it well because when it happened, I was like having an out of body experience. The images, people, the lights, the ambience, laid out before me like a picture, and I was like watching a movie, and I sort of know that I saw this movie before, how it went. I lasted for about 30 seconds. To me, it also seemed like it was in the past, rather than the future. The feeling was weird and yet wonderful at the same time. I don't really know how to explain it, perhaps it was memories from my past life? :D

I have had this happening to me since I have been a little kid and cannot explain it! But I LOVE when it happens! I would LOVE to know how scientists explain it! There is still SO much we cannot explain!-Isn't the world great?!

I have read that it is our mind tricking us and that these memories are not actually true but they are thoughts made so that our old memories can be cleaned. I'm not completely sure about it either, but I tend to believe that. Have a Wonderful day.

Hello Hayley_N, Yes I do believe is preconnition because it happen to me many years ago. My mother to me to a church when I was a child for the first time and I said to my mother that you can go right round the bach of the church and there are diffodils growing at there,she told me not to be silly because I've never been there, I insisted nd ran round the back, yes there were beautiful yellow daffs all blooming, so I shouted to mum "come and see" she was so suprised. I have ner been there so How did that happen? it still gives me the tingleing feel when ever I think about it. So You may be right. Regards. Tamaraheart.

I am not sure, sometimes I think that our mind plays tricks on us, at other times I think maybe we share memories with our ancestors somehow, and that is why we feel like we may have been somewhere before or done something before, but i really do not know.

I have friends who claim their dreams are foretelling dreams. I do believe them. But as for me, so far my dreams seem like a manifestation of my thoughts. If I keep thinking about something or someone, I'll somehow dream about it. I also had deja vu instances before. All I felt was the scene, people and their actions are seemed so familiar. However, I am not sure if I saw it in a dream or not?

I have had deja vu my whole life. LOL!!!It's alway spot on. When I have the dream I write it down if I remember it and I try and describe it. LOL!!! Sometimes it's scary when it happens Like I had a dream that I was in this house looking at the wall of pictures and then woke up didn't know who's house it was or where I was 2 yrs later I was dating this guy and he wanted me to meet his family I walked into the house and saw the wall of pictures what was really freaky is I had it written down. LOL!!!

This is an interesting subject to debate. I have had deja vu for most of my life, though I don't get it so often nowadays. When I was a courier, I cannot count the times that I have thought, or said, "I've been here before ..." or "I remember doing .. before". Sometimes I used to get it so strongly that I could say what the following few seconds were going to produce - I SWEAR THIS IS TRUE - it didn't happen every time though. The best explanation that I have understood is that deja vu happens because we have indeed done it, or been there, before ... only in a former life. I don't know if that is true or not, but it seems to make a rational answer to the question of what deja vu is.

We are energy. When we die, our energy continues into the universe. Every sound, every movement, everything we are circulates into the galaxy. It is possible that WE are experiencing some one else's memories and actions. It is also possible that it is familiar to us because we have premonitions which come to us in dreams. We dream every time we sleep, we just don't always remember it in our waking state. There are all kinds of theories about deja vu but, who knows, reall?
