I did LSD on a very low dose months back, and it was okay, but I took too little and didn't really experience much. I even slept properly after like 6 hours.

I took it again the day after having a bad experience on MDMA (thinking I was having a stroke, what felt like some kind of psychosis? Delirium? Hallucinations.) I took too much, took 2 tabs (labelled as 350ug each but probably far far less). Was terrible. Traumatising. And the whole trip was based on the prior night, and yet again I became convinced I was having a stroke, the experience from the night before carried on over into the lsd trip. By that I mean, I started to believe I was dying. It started off with the thoughts, and then these thoughts became real, physical sensations. I felt waves of pain based off my thoughts. Very real pain. I assume it was pain synthesia. I'd get an image of something, like a thought of me having a stroke and then I'd get the imaginary symptoms to go along with it. Agonising pain. I still remember it. Ended up hysterical, calling the ambulance because I utterly believed I was having a stroke. I didn't have any hallucinations, just pain and feels. Music made it worse. My boyfriend would put on Eminem and the pain was agonising, and I now think this is because emotional and physical pain are very close. So any time I was feeling emotional pain, anxiety, etc it would become physical. I ended up going to the hospital. They said I was fine but I didn't believe them. I ended up needing to be restrained. I was scared of losing control, felt like at any moment a switch would flick in my brain and I'd attack someone or myself I started to believe I was crazy. I even went crazy. I wasnt even myself, just talking to myself out loud, muttering random words, acting like a full blown schizo. I spun a qhoke story in the head that night, once I stopped believing I was having a stroke I started believing I had lost my mind, that the hospital were going to section me, that I'd be locked away forever).

Anyway, , this passed and I recovered quickly, went home the next day. Didn't do LSD again.

I smoked some THC (weed liquid) last night and I felt like I did on LSD. The only assurance I had was that this would pass. I felt exactly like I did on lsd minus the total brain fuck. I felt incredible pain all over my body, briefly became convinced I was having a stroke, had some derealisarion and things would slow down and speed up. My heart was going crazy in my chest, and I nearly called the ambulance again. I didn't. After about 1.5 hours of this, the anxiety went away but I was still left with the physical pain all over my body, my legs in particular. This didn't pass. It only went away when I slept 10 hours later. So I was in pain and aches for like 10 hours following the THC. I'm fine now, pain gone.

What is this?
