A few years back, I had an incredibly vivid dream that seemed to be real. One of the characters in the dream informed me that my whole life had been a dream, and I didn't believe her. We got in an argument, where I pointed out how vivid and detailed my surroundings were, how vivid and detailed my memories of growing up in California were, and how unlikely it was that a character in my own dream would disagree with me. The character challenged me to try to open my eyes, and I did, confident that they were already open. I opened my eyes, and it was 3:00 in the morning in my little apartment in Texas. I have never even been to California. My entire life had been a dream, and a small fragment of my subconscious had known it was a dream when I had not. I was a solipsist for the rest of the week.
Why did you cease being a solipsist after having such an experience?
This is a kind of "X files" thread.
Post experiences which spooked you, which made you doubt reality, mathematical or physical laws, your sanity, memory or perception. The more improbable the better, but no second-hand legends please, share only what you personally experienced. If you had the event later explained rationally please use rot13 to avoid spoilers.
