I was at a concert a while back looking for molly in the parking lot before the show. I see a guy and his girl outside their car drinking some franzia, strike up a conversation, and end up buying molly for myself and my two friends. The seller warned me that it was VERY strong and would "have my eyes rolling back in my head." The guy also said that the molly was heroin based, or cut with heroin. Whatever. I know, I know, buying from people you don't know is risky, but we were in a pinch and they seemed like a genuinely nice couple. If you've done good/pure molly enough times (even a couple times, really) you can identify, at least to some degree, how potent the product is by tasting the powder and seeing how bitter it is. We tried it and it tasted very strong so we thanked him and headed in for the show. Keep in mind that one of my group and I were experienced at rolling, but the other had never tried it. The friend who had never taken ex before (we'll call him B) took a smaller dose and had none of the after effects I am about to mention. The other friend (this will be J) and I took, over the course of the show, roughly 1.2 g each and it was the one of the best feeling rolls I've ever had. I felt great all the way through the show and had plenty of energy, but this was the kind of roll where I was getting a little sloppy and loose with my movements. After the show was over, I still felt noticeably lifted and slightly euphoric (and continued to feel as such until I fell asleep at our hotel comfortably close to 2 hours later, another aspect that made it one of the best rolls I've had), but felt distorted enough that I had B drive us. After a short while riding in the car, I took notice of some typical, orange cylindrical construction site cones (the ones that are about 3 or 4 feet high). As I was watching them through the window while we were at a stop light, before my eyes several construction workers in hard hats and reflective vests morphed out of the road cones. I will stop to say that this is THE most convincing and realistic hallucination I have ever had. It was not distorted, I did not notice any other abnormalities other than lights being overly bright, just this very realistic scene that my mind played out before my eyes. As I watched, the construction workers stood up and started to move as if getting up to walk somewhere. (I assumed to get to work) I was in awe and completely captivated, but as I looked away for a fraction of a second, the hallucination was gone. The entire event took less than 5 seconds and it was back to plain old road cones. I tell my friends in the car and they are not having anything similar, but I do not worry too much about it. We arrive at the hotel we were driving to to meet up with some people from the show for a little hotel room after party. As I sit in the room with 15-20 people, the dealers original prediction comes true, and my eyes start rolling back in my head if I relax them. This turns into an inner struggle of trying to keep my eyes down to a normal position. Having seen this before in others and knowing how I must have looked, I immediately felt uncomfortable in the room and wanted to leave. My friends were tired anyway, so we went back to our own hotel. I can still say at this point in the night that I feel abnormally good, and the body high from the molly was still quite noticeable and enjoyable. All three of us were in bed at this point in our single room hotel room, and the lights were turned off. I could keep my eyes closed and felt pretty tired so I figured I wasn't going to have trouble sleeping, but as I lay there with my eyes closed I hear J say my name. I respond, but J was confused as he had not said anything. I heard this several more times, and being half asleep, I had the same response every time. J soon mentioned that he could clearly see a ceiling fan on the hotel room ceiling, when there was not one, or even a light fixture. His description is similar to mine from earlier in the car. After all this is done and I get the auditory hallucinations I am experiencing under control, I fall asleep. The entire experience from the time we left the show to the time I fell asleep had the usual signs of a comedown off molly, just a more gradual one, as we finished our last dose late in the show. None of these happenings, besides the one part in the hotel room, were necessarily unpleasant, just very...strange. My hallucinations happened 1-1.5 hours apart and seemingly had no trigger or invocation. I have dosed LSD and eaten mushrooms as well as quite a few other drugs and drug variants, but have never come across anything quite like these hallucinations. Hope this helped. Or at least entertained. Let me know if you've had a similar experience, I am very curious as it was probably one of the weirdest drug related experiences of my life.
