So I take hours to fall asleep if I’m on a day shift schedule (I can go to bed at 9 or 10 and still be awake come 4 or 5 am) but when I work night shift and go to bed at 8 or 9 am I’m asleep within 15-30 minutes. I don’t usually dream that often, it seems to correspond more with my mental health. If I’m going through it I dream more. I think it’s both an escape mechanism and my brain’s way of processing things. Normally I don’t notice I start dreaming right away when I am in a full night’s sleep, but I’ve definitely hit the 5 minute snooze on my alarm, fallen back asleep, and had an entire intricate dream before the alarm woke me up 5 minutes later. I can also get incredibly amazing 3 minute long power naps and go from being dead on my feet to completely refreshed and ready to go for hours. No surprise, my sleep schedule is fucked. I work nights and go to school days and sometimes go 24-40 hours without getting sleep and actually function pretty well.
This sounds like something you would do if you have already robbed a bank and you need to get rid of the dyed money. Buy your own dye, withdraw your own money, dye cash that you can prove is legally obtained, spend it in a bunch of places and make it a “thing”, become known around town as the “crazy dyed cash dude” then start throwing your illegal cash into the mix.
