"Feelings of déjà vu and premonition seem spooky, even paranormal. But when we understand the common tricks our memory plays on us, there’s nothing unusual about either of these eerie experiences. "

It's interesting that feelings of deja vu can be created by such laboratory experiments. However, the fact that similar situations to ones actually experience in the past can elicit feelings of deja vu, does not mean that this is the cause for every experience of deja vu. It's still at least possible that we have deja vu experience for situations unlike anything we have experienced before.
