Saw it in 1962
This was the first movie that I went to see by myself. I was 11 at the time and I had gone to see Earth Vs. the Flying Saucers, Twenty Million Miles to Earth and House on Haunted Hill with my brother at the local theater. One afternoon I told my mother I was going to visit a friend but headed over to the theater, paid the thirty five cents admission and twenty five cents for candy (boy was I rich) and in I went. The movie scared the hell out of me and by the third dream like segment I was covering my eyes under the 3D glasses. I still have the glasses although some rodent ate the red plastic sheet lens out of them (it probably had a psychedelic experience like Dr. Barnes). At supper time that evening my uncle who hung around the bar near the theater quite innocently asked me if I liked the movie. My mother never caught on. An excellent experience for a young boy I must say. One of many to follow.
The theater was unusually full and the reaction was quite loud whenever we put on the glasses. Lots of oh's and yucks. I recently saw this again and you know what, still a little scary. I guess the boy never completely grew up.
