i realy love déjà vu, like its one of those moments where your brain completely tricks you and your certainty of reality comes crashing into conflict with actual reality.
"ive seen this before", and you have, its just your brain has temporarily forgotten that "before" isn't meant to include the split second that your body takes to bring everything together into parity and call it "now".
déjà vu is the perfect example that you can never fully trust yourself. you're not an all knowing being, you will make mistakes and thats okay. So it's importnat to trust and rely on others.
