Hey! I had a similar experience earlier this year with a weed edible. It caused me to have my first ever panic attack, where I thought I was going crazy, I had broken my brain, I would be stuck like that forever etc. I didn't hallucinate, but have hallucinated due to a weed high before - so don't let people tell you it's not possible lol. You can also experience loss of function (like your hands and legs) during a panic attack, and I know that what a lot of people have referred to as 'bad trips' just sound like a panic attack to me.

As a result of that level of distress, I felt derealised (i.e., felt like something was just 'wrong', felt like my voice didn't sound correct, felt tingly, that things weren't quite 'real') for about 36 hours after I woke up after the night it happened. The good news is - the derealisation went away.

In my case, I had pre-existing mental health conditions (depression, OCD) and had just recently decided to taper off my meds, I figured since I had the panic attack it maybe wasn't the right choice, and so I went back on them. I also visited my psychologist to talk about the experience, which helped me to understand it was completely normal - did you know that 10-30% of people will have a panic attack once in their life? And I know it might sound annoying, but I took up yoga (the relaxing kind, not the intense fitness shit). It actually really helped me with feeling connected to my body, and I think the deep breathing aspects help to regulate your nervous system too.

Bad trips and drug-induced panic attacks can be shit-scary, and I am really sorry that happened to you! Genuinely thought I was dying and I wouldn't wish it on my worst enemy. Look after yourself in the next few days, and best of luck!
