I watched that Pink Floyd movie just once. I was sane and sober. It made no sense to me.
I had one really eerie experience with Pink Floyd. Back in the mid 2000s, I was walking down a rail trail in the Cedar Rapids, Iowa area.
Now this rail trail went miles and miles through corn fields and you could really get far away from civilization. So on one of those days, I'm listening to Pink Floyd music on my iPod and during one of the songs, I heard these sirens. I remember thinking that I never remembered sirens in that particular PF song, though it is not unusual to have weird sound effects in their music.
Turned out it was the TORNADO sirens going off! I took out my earphones and realized that's what those sounds were. I looked behind me and saw this incredibly dark purplish cloud bearing down on me. Right out of Wizard of Oz!
I was more than two miles from my car at the time.
A cool breeze suddenly materialized with patters of the largest rain drops I ever saw. I thought for sure I was in serious trouble. But the heaviest of those clouds passed on to the left of me and all I got was a little wet. Later on I found out a tornado touched down maybe 5 miles from where I was walking. The corn was hardest hit, fortunately.
