To experience Déjà vu, as I was once told by a video game playing friend, is when you have died in real life and gone back to a previous 'Checkpoint'. Déjà vu just means that you can remember something from a life lost.
Me: Whoa, weirdest feeling of Déjà vu

Nathan: Whatever you think you should do, don't do it. It didn't work last time

Me: What the fuck are you on about?

Nathan: Mate, you lost a life just be careful, you don't know how many you have left

When an experience happens, you might feel like you've gone through that experience in the past even though you haven't.

Déjà vu is the experience of being certain that you have experienced or seen a new situation previously – you feel as though the event has already happened or is repeating itself. The experience is usually accompanied by a strong sense of familiarity and a sense of eeriness, strangeness, or weirdness. The “previous” experience is usually attributed to a dream, but sometimes there is a firm sense that it has truly occurred in the past.
Dude, I get Déjà Vu all the time.

n.

1. Sarcastically highlights moments in film or television that viewers find trite; inferring the moment is cliché, and could’ve been used in the trailer, preview, or sneak peek, as a means of generating hype. When used, the term embodies a condemnation of Hollywood cinema, the failure to innovate, and a reliance on cinematic clichés as a means attracting, and maintaining the appeal of a broader audience. Examples are often defined as corny; and identified in scenes described with intense action, powerful emotion, witty one-liners, or general “awe”.

Not to be confused with Trailer moment; Trailer déjà vu refers to instances not actually found in the theatrical trailer, preview, or sneak peek.
That scene just gave me a wicked case of trailer déjà vu; it was so corny, I can’t believe they didn’t use it in the trailer.
