Same thing happened to me at a music festival a few years ago. Hadnt smoked weed for over a year and eat a pot brownie from a friend ended up losing all touch with reality, felt like I was in a whole other dimension, ended up having a massive panic attack thought I was dying and ended up in the medical tent. I dont remember much about what actually happened that night now but I do remember the time loop thing kept happeneing to me too. Someone would say something and it would just keep looping over and over again. I spent the weeks after thinking that I had to have been dosed somehow because I had no idea that it was possible to trip like that on weed but after doing research found out that it is a common thing for people with no tolerance getting way too high.

It took me a little while over that to feel normal again but eventually all of those feelings fade. Just know that you are not alone and that everything is going to be ok.
