What was the worst case of dejá vu you have ever experienced?

Oh I have a good one for this.. But it requires some background. I was going on a date with this girl and she had pot gummies and ate like 5 of them. I have no tolerance way I figured just one will be good for me. It turns out they were 25mg and she didn't think to even mention that because it turns out she has a crazy high tolerance.

We go to a bar and I order food and drinks and I get to the point of taking a sip of mine and realize that we need to go home. I was having trouble keeping my head upright was how bad it was. So we call an Uber, it feels like it takes 5 years to get there and then we head back to be place as I'm just passing out in the car ride.

We there and I basically have to lie there on the couch as I'm about comatose at this point and she puts on a movie, this is where we finally get to ops question. As the movie is playing and I'm lying there listening to it, I feel with absolute certainty that I know what words the actors are going to say next. I have never seen the movie, mind you, but I feel certain. I felt so certain that I was about to start saying them aloud because I thought that really would've blown by date's mind.

But, despite this certainty, there was some part of me that said, this is really irrational-- let's predict it in our head and then see if it lines up. Not only did it not line up, it was consistently not even in the same ballpark. My predictions were not at all like what was being said and yet I still kept telling like I knew with certainty what would be said next. My one big regret from that night is that I never said any out loud because they would've been hilarious nonsense.

So that's my story of the only time I felt like I had deja vu but it wasn't really at all.
