MDMA is about empathy above all else. A feeling of warmth and closeness and intimacy and caring in situations where those emotions either don't exist or they exist in "lower doses". Difficult to depict in isolation. But - and I think this is critical - easy to depict by way of contrast. Before, during & after. There is no dramatic perception change or distortion of physical reality. It's subtle. It's emotional: "I love you now but I won't tomorrow". Maybe "love" is too strong. "I care now but I won't tomorrow"? It's easy to hold hands with someone whilst taking mdma. Easy to hug. Not even necessarily sexual. Music & sound? Not convinced. It's a peaceful time of silent caring. Soft edges. The (dance) music is the same. But these things are quintessentially personal experiences which are difficult to characterise or bind by generalisations. Tim
