Hi, welcome to the forum!
Dropping by to say, firstly there is always a practical quality to dreams, the older you get the more you naturally are able to predict your life (especially if things are not changing a lot) and the more chance there is for de ja vu like things to happen.
HOWEVER, I don't think that explanation really captures the uncannyness I tend to feel about de ja vu moments.. I very much do believe in physic powers, both as a byproduct of being perceptive, but also as a genuine force beyond what can be known.
That, beyond what can be known, bit might be important though, I suspect the more you try and grasp at de ja vu, the more it will slip through your fingers, it's meant to be a glimmer in the corner of your eye, its natural home is in mystery, and that should be respected.
Being perceptive is always a good idea though, Id keep an eye on it!
