Is it normal feeling like you already experienced a moment

Yes, it happens to lots of people. You get this weird feeling that you've somehow experienced an event or moment before, but you have no idea when or where.

déjá vu- is the experience of feeling sure that one has already witnessed or experienced a current situation, even though the exact circumstances of the previous encounter are uncertain and were perhaps imagined. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness", "strangeness", "weirdness", or what Sigmund Freud calls "the uncanny". The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience has genuinely happened in the past.

Does this describe anything like how you feel.

Extrasensory perception (ESP) - Involves reception of information not gained through the recognized physical senses but sensed with the mind. ESP denotes psychic abilities such as telepathy, clairaudience, and clairvoyance, and their trans-temporal operation as precognition or retrocognition. ESP is also sometimes casually referred to as a sixth sense, gut instinct or hunch, which are historical English idioms. The term implies acquisition of information by means external to the basic limiting assumptions of science, such as that organisms can only receive information from the past to the present.

Sounds more like déjá vu to me personally.

it happends to me but the times that i have that feeling is not important. and it IS déjá vu(thats how you write it people)

OMG finaly someone who understands my feeling man.

It's Deja Vu. DUH

Happens to me all the time but I wasn't sure if it was dejavu haha

Happens to me constantly, i generally day dream about whats going to happen, change what i was doing, for example driving too fast and then 10m down the road a police car is parked round the corner watching passing traffic. JUST AS I SAW. Its a useful gift, who cares if its normal, just enjoy!

There are so many things that are strange in this world but have an explanation. But this doesn't have one, right?
