I did a lot of research while writing my script. Below is a collection of images I found most comprehensive while trying to fully understand to cycle, and that helped me decide what I could compare the stages to. I had the following links open throughout the process, A dictionary of 60s slang and the best explanation I found of the cycle.
Here is a guidebook of sorts explaining different references I researched in my script
