What exactly is Deja-vu?

Question

Is it a good or bad thing?

What does it mean?

Answer 1

It is neither good nor bad. Deja vu is the sensation of seeing something you thought you just saw or recently saw in the exact same way. Say you dream about something and it turns out to happen to your best recollection the next morning. That is a form of deja vu. Science offers and explanation for deja vu in situations where you see something twice and think it is the same instance. Normally your short term memory receives the information first and waits to compile the important information into you long term memory later. In deja vu instances it bypasses the short term and is stored in the long term causing a feeling of deja vu
