Put it this way. Over the course of 12 hours, how many times does your mood change? Before your first cup of coffee, after a long day at work, getting stuck in traffic, going for a bike ride, feeling the embrace of your significant other. Seeing them flirt with your best friend, and your best friend flirting back.

Now, take any 4 weekends from the past six months and compare them, what was on your mind for each Saturday and Sunday? Count the things you might think about in a span of time for any day off.

Now, imagine that thrown into the middle of that, your friend shows you, in the palm of their hand, two tabs of acid.

Add psychedelic state to all your shifts in mood, stream of consciousness and common distractions, and dredge up the baggage of memories reaching back into your childhood, and include existential questions about what it means to exist.

It could be chaotic-but-deterministic, rather than random, and the above description could still be accurate.
