Same here... I sank into actual quicksand ( not mud or clay ) at a quarry when I was in my early teens. It was a cold autumn day back in the '70s. I was wearing a beige poloneck ( turtleneck ) under a charcoal grey knit V-neck sweater with a pair of denim jeans and sneakers.
I stepped a yard onto a sand bar which I had tested with my right foot and immediately sank in up to my knees. I stood still and shuddered as I continued sinking. I was excited, but scared as I wondered when I'd stop sinking, imagining all the scenes I'd seen on TV and in comics.
I couldn't feel bottom yet and after a minute, I'd sunk in up to my hips. The cold I felt was immense and I hoped I wouldn't go in any deeper. It was now brushing the hem of my sweater and I looked around to see if anyone else was there. I was alone.
I sank about another inch when the sinking had stopped with only the top half of my body above the surface. I stayed still, apart from the involuntary shivering and chattering of my teeth. Stupidly, I didn't have a plan on how to free myself ! I leaned back and could feel the damp, but solid earth with my hand, and thought if I could turn around I'd be able to drag myself out.
Doing that was harder than I thought and after several minutes I had to give up. " I'm stuck ! I'm stuck ! ", I gasped. Fortunately, I hadn't sunk any further.
There was nothing else for me to do but yell for help, I thought... but who'd hear me ? I may as well be bound and gagged in a cabin cellar deep in the middle of a forest !
I had to try something else. By trial and error I accidentally found if I leaned to one side and moved the opposite leg, I managed to pull it out a little. I then wriggled my foot and made circular motions. I could gradually feel my leg coming loose !
Eventually my left leg was entirely free. I rested it on the surface with my knee crooked and after I took some deep breaths, leaned over to the left and worked the other leg free.
I then crawled backwards onto solid ground. I was happy, but FREEZING. I'd have to get home as fast as I could go. Luckily it was only a fifteen minute walk and I went straight to the shower after quickly explaining to my mother it was a stupid accident.
After that I was barred from going anywhere near the quarry
