Deja vu with anxiety?

So today and yesterday were both great days for me. But today after school i did experience deja vu, severely i feel, and it kinda scared me and made me feel like i was dreaming again. Since I've taught myself a new technique the dreaming feeling isn't that bad but how severe the deja vu was. I was having a conversation with a guy and some friends, and he said the exact sentence i felt like i had just heard. Like i literally felt like i just heard his exact words in my ear, but i just didn't hear who said it. So I asked him did he have a conversation like this earlier with someone cause maybe I over heard him but he told me know. I still feel almost 100% sure i heard someone at least say something similar earlier today... can anyone relate?

tr4y,

I typically can't remember whom I tell what to or when, but that I told somebody at some point. I'm a trustworthy person because I feel I have to hear something twice to make it a fact, otherwise I might have dreamt it. lol

Thank you everyone so much! All your support really means so much to me!
