пожалуйста перевод it’s a strange sensation. A new place that seems familiar an event that you’re sure has happened before. How many of us have had this experience? Apparently over 70%. It’s called déjà vu and according to the experts it’s not something new but has been happening to people for hundreds of years!So, what explanations are there for this strange feeling that is both confusing and uncomfortable? Some scientists think it is related to dreams and memory. It appears that although the majority of us cannot recall our dreams, we actually store the memory of dreams inour long term memory. This deep memory can comeback sometimes when we are in a similar situation andmakes us think that we have done this before.However , as usual, not all experts agree. Those who believe in reincarnation – the idea that we have all lived before – say that these feelings are fragments of memories from previous lives. But, whatever the reasonfor déjà vu, one thing it does show is how complicatedand amazing our brains are and that we are a long way from understanding completely how the brain, and inparticular, how our memories work.

и Are the sentences true or false?
