That is chem induced panic attack, it makes you wanna run for miles.
Doesn't need to be LSD induced, I think that is some sort of med.
My doctor prescribed me some allergy pills because I had a reaction to some plant. Rash stopped, but a problem was that I had exactly the same symptoms like you. The difference was that I knew what it is from, so I didn't panic at all.
I never experimented with anything because I was hospitalized at one point of my life and most of the narcotics don't work anymore. I also don't feel pain in some parts of my body, they told me it is not a brain problem , nothing burnt inside but the fact is that I do not have desire for any chemistry and as far I can tell I can't develop any addiction because my neuro-signals are really weird, so I think some things are a little different.
