This happened a while ago in Dec 2022

Was out with a friend, idt we had any drugs aside from a nitrous tank. We fill up the first balloon and do it at the same time

It’s kinda hard to explain what I personally experience, but basically I looked at the sky, and idk if others have experienced this too, but my vision will kinda just freeze whilst I’m staring at the sky. Then I’ll be thinking to myself “hang on, wtf am I looking at?” like my visual perception/understanding kinda just deteriorates and from my perspective, I am just looking at some weird shapes and colours, not realising it’s the sky

Anyways eventually when the high finishes, and I start “coming down” I’ll realise oh yeah, I’m looking at the sky. As I’m coming down my friend says “that was so good” (something along those lines) as he’s coming down too

Then we do another balloon. This is where things get really mind fucky for me. In short, I basically experienced the same chain of events: look at the sky, confusion, come down, and by far the weirdest part: my friend saying the exact same line again

At that moment I kinda questioned reality. The whole sky thing isn’t that weird, but my friend repeating the exact same line is what really confuses me, as it’s something external/not influenced by the high, if that makes sense

Not the most insane story ever, but was a crazy sense of deja vu and something that was trippy as fuck for me lol
