You have just answered a 3 year long mystery for me!! I picked up what I thought was MDMA from source in Chester to take with me to the warehouse project. Anyway, half way through the night i swore i could see everyone wearing bloody glasses!! I could see assorts of other shit too, umbrellas, people with face paint on, some really crazy stuff! I also remember it being one of the best highs going, got pretty intense at some points and made me borderline para for a good while. Defo up for it again though
