Oh yeah, I did that by accident when I caught Mono in my early twenties... just bizarro world. I forgot to mention that I did mescaline a couple of times too but it never made me feel as odd afterward as the acid did. Once when I was coming down off an acid trip my best friend found me sleeping with my eyes wide open and got really freaked out when I woke up and said good morning in the middle of our "conversation". I only mention that because acid is just a weird, weird drug. I know a lot of people for whom it's triggered anxiety & panic. My symptoms have gotten better over time so with any luck yours will too.
Edited to add - same here with the carpet, clouds, wood grain... just about anything if I'm paying enough attention. I don't mind that part as much though lol.
