Fake molly

Around 2 weeks ago I got half an oz of what was supposedly mdma to try for the first time. It looked normal (in rock form) and I had some friends confirm it looked fine. My dumbass dosed without a test (around 150mg). At one hour I started feeling it but it felt more similar to the come up of acid and I wasn’t getting much euphoria. There was a good amount of panic and anxiety and the peak was really weird. I started seeing bugs and spiders when I looked somewhere for more than 3 seconds. I would look over at my friend and his outfit/appearance would change every minute or so (wood sculpture, tail with cat ears, black suit with a top hat) and any words I looked at like on my remote would be inverted. The high felt euphoric while being completely confused the whole time. When I would close my eyes I’d randomly start playing Minecraft or watch a completely fabricated show. After I woke up my vision was still blurry and I’d see bugs every now and then. I had the most miserable week of my life until I felt normal. Does anyone know what this mystery substance could be? Ps: I’d also have frequent audio hallucinations too.
