I accidentally dosed way more LSD than I intended this way. I figured I'd been ripped off and it was super weak. Turned out I was stoned and the past hour had actually been about ten minutes. It was pretty frightening; I thought I might lose my mind.
That night, I discovered that I could slow down music and step through the parts of each instrument and examine what they were doing. After doing that several times, I got a headache and laid in bed watching the ceiling. I'm really glad I didn't do noticeable damage.
