Déjà vu - all over again

I had such a feeling of déjà vu at work today that it made me feel sick. It wasn't anything bad, it was just the fact that my mind can trick me like this that made me ill for a second. Btw, did you know that déjà vu probably is a delay in the perception of a situation? In other words, when you're really tired your brain might actually go so slow that you might not register something until after it's happened. Or, in the much more eloquent words of Wikipedia: "The events would be stored into memory before the conscious part of the brain even receives the information and processes it".

Thank you, Wikipedia.

In other words, when you experience a déjà vu, it means you should get some rest.
