Mar '17
Mine was back in 1990. I was only 18 years old. Me and my mate went to the drive in for an all night marathon. I can't even remember the list of films that was playing. I remember falling asleep and waking up around 2am just as Jacob's Ladder came on. I'd never heard anything about it and thought I was in for a war film at first. I was a bit bleary eyed at first but was soon wide awake and blown away by it. A magnificent surprise experience that you just cant recreate.
Another time, I got sooo baked and decided to try out "Humanoids from the Deep", which honestly blew me away. The next day, I had forgotten most of what happened in the movie, so I got high again and watched it for the "first" time again. That process continued for about a week, until I finally remembered the movie in full.
