I have had some very interesting auditory hallucinations on Mary. One day when I had spent just about the whole day smoking a few friends came over to toke and we decided to jam afterwards. So I'm standing there playing a bassline, listening to the two guitar parts my friends were jamming on, and it sounded like laughter. They were both strumming at about the same time and I swear to God there was something about it that just made it sound exactly like a girl laughing. I even stopped playing and started laughing too and my friends were like "WTF DUDE WHY'D YOU STOP?" and so I said that what they were playing sounded way too much like laughter for me to continue. They had no idea what I was talking about. It was a metal riff.
